1 Introduction
Electronic engineers working in the automotive area are sooner or later faced with a cranking test pulse.
These test pulses describe the drop of the battery voltage during cranking of the engine, and each car
manufacturer has its own standard for them. The attachment of many electronic circuits to the battery
results in cranking pulses impact ing them. In some applications like the navigation or multimedia system,
an interruption of operation due to the drop of the input voltage is unwanted or even unacceptable. In this
case, the most-often-used solution is placing a boost converter in front of the circuit to provide a stable
input voltage for the electronics.
During the development process, one must test the functionality of this kind of pre-booster (as, for
example, in the TPS43330) to ensure a fast start-up and a clean and stable output voltage for the
subsequent electronics, like point-of-load converters. Also, point-of-load converters which are directly
connected to the battery require testing, as the input voltage can drop very fast and the converter must
react fast enough to keep the output voltage constant.
To test automotive electronic systems with up to 50 W of input power with different standardized cranking
pulses, one can use the HVAL068A board.

2.1 Board Overview
Figure 2. Board Overview
The board consists basically of eight sub-circuits:
• An input filter to reduce the noise of the buck converter on the input cabling as well as active reverse-
polarity protection
• A synchronous buck converter providing the power for the output
• A VID interface to adjust the output voltage of the buck converter
• A trigger circuit providing an external trigger signal when a pulse is generated, as well as a trigger
input to start a pulse from an external signal source
• A user interface with push-buttons and LEDs

Operation www.ti.com
• A bias power supply to supply the microcontroller and all other circuitry
• A microcontroller to control the complete system
• A programmer interface to program and debug the microcontroller by Spy-Bi-Wire
2.2 Input/Output connector Description
2.2.1 Terminals
Power Input is the input plug for the board. Adjacent to it is the GND reference ground. Use those
banana plugs to attach the EVM to a power supply which provides 24 V and at least 3 A.
Power Output is the output plug for the board. Adjacent to it is the GND reference ground. Use those
banana plugs to attach the load or device under test to the board.
Ext. Trigger Out is a BNC connector providing the trigger output signal. The board generates a
rectangular trigger pulse (0 V to 3.3 V) with a duration of 10 ms at the beginning of each cranking pulse
for easily triggering an oscilloscope.
Ext. Trigger In is a BNC connector for a trigger input signal. A rising edge (>2 V, 5 V max.) generates a
pulse on the output.
2.2.2 User Interface
Output Enable is a push-button to enable the buck converter and therefore provide a voltage on the
output. Adjacent to it is a green LED showing the status (on – enabled, off – disabled).
Program is a push-button to select one of the three programs. Adjacent to it are three green LEDs
showing the selected program (1, 2, or 3).
Single Cont. is a push-button to select between single or continuous pulse generation. Adjacent to it are
two green LEDs showing the selected mode (S or C).
Trigger is a push-button to start generating a single pulse or continuous pulses. Adjacent to it is a yellow
LED which is on as long as pulse generation continues.
Delay is a potentiometer to set the delay between pulses in continuous mode.
2.2.3 Jumpers
J13 is the jumper to disconnect the supply voltage supervisor (TPS3809K33) from the reset line of the
microcontroller. The debugging and programming processes use the reset line for communication between
the debugger interface and the microcontroller. To give full control over this line to the debugger interface
requires disconnection of the supply voltage supervisor, as it has a push-pull output and not an open-drain
output.
2.2.4 Programmer Interface
J14 is the connector for the debugger interface for debugging and programming the microcontroller. The
pin configuration fits the MSP430 USB Debugging Interface (MSP-FET430UIF).
3 Operation
The supply voltage range for the board is 20 V to 28 V dc. The power supply must be capable of providing
at least 3 A. The output voltage range is 2 V to 15 V dc (limited by the hardware) at 50 W of output power,
maximum.
After applying the supply voltage, no voltage is present on the Power Output connector and the following
LEDs are shining:
• Program – 1 (Program 1 selected)
• Single Cont. – S (Single mode selected)
By pressing the Output Enable push-button, the buck converters start to operate and the default output
voltage for program 1 is present on the output connector (12.6 V).

www.ti.com Operation
To start generating a pulse, press the Trigger Input push-button. The resulting pulse lasts approximately
10 seconds, during which time the adjacent LED is always on. To abort generating the pulse, press the
Trigger Input push-button again. Then the output voltage goes back to the default value (12.6 V) and the
LED turns off.
The Program 1-2-3 push-button selects one of the three available programs. Each keystroke counts one
program up. After selecting the third program, the next keystroke jumps back to program 1.

VID Interface www.ti.com
Figure 5. Program 3, 2 s/div – Volkswagen Cold-Start Test Pulse, VW80000
The Single Cont..push-button selects between generating a single pulse on an input trigger event (push-
button or external trigger input) or continuous pulses until the next input trigger event.
In continuous mode, the Delay potentiometer adjusts the delay between successive pulses. At the
counterclockwise limit, the delay is 0 seconds; at the clockwise limit it is around 2 s. The gradient between
those two limits is linear.
Changing the program is only possible while no pulse generation is in progress. If the program is changed
during pulse generation, the board is registers and stores the new program selection, but the change does
not occur until completion or aborting of the present pulse and occurrence of a new input trigger event.
Changing the mode from single to continuous is also only possible while pulse generation is not in
progress. In the case of a mode change during pulse generation, the board registers and stores the new
mode, but the change does not occur until completion or aborting of the present pulse and occurrence of a
new input trigger event.
If the board is working in continuous mode, pressing the Single Cont. push-button switches the C LED off
and the S LED on. The generation of the present pulse finishes and after that, the output voltage goes
back to the default value. Now, for a single pulse, a new input trigger event is necessary.
The Output Enable push-button enables and disables the output voltage independent of the selected
program, mode, trigger event, or anything else. With it, one can always switch the buck converter directly
on or off.
4 VID Interface
To change the output voltage of a converter during operation, several approaches are possible. Probably
achievement of the fastest output voltage changes can be by using a VID interface (dynamic voltage
identification), known from the area of powering DSPs (digital signal processors). Depending on the
processor load, the VID interface adjusts core voltage to increase the computing power or to reduce the
losses.

Figure 6. VID Interface
One can change the output voltage of a converter either by changing the reference voltage or the voltage,
which is compared with the reference voltage. The reference voltage is usually fixed and not accessible on
the controller, necessitating use of the second method. The circuit contains several additional resistors in
parallel with the low-side resistor of the voltage divider, with small FETs to switch them on and off.
The addition of eight resistors and FETs in this circuit results in a resolution of 51 mV within the output
voltage range of 2 V to 15 V.
A microcontroller, MSP430F2274, controls the VID interface as well as the complete system. The MCU
has three different hard-programmed cranking pulses.
• DaimlerChrysler Engine-Cranking Test Pulse, DC-10615
• Volkswagen Warm-Start Test Pulse, VW80000
• Volkswagen Cold-Start Test Pulse, VW80000
4.1 Modifying the Cranking Pulses
Changing the implemented cranking pulses to your own needs requires modifying the source code of the
firmware. This section describes how to adapt the firmware.
Import the zip file containing the original firmware into Code Composer Studio (CCS) using the Import
function. For more information on this topic, use the Help function of CCS. Also ensure that the version of
CCS in use is the latest.
The firmware project contains several files. To change the pulses, only the pulse.c file requires
modification. Inside this file, the three functions
• void generate_pulse_program_1(void)
• void generate_pulse_program_2(void)
• void generate_pulse_program_3(void)
define the form of the pulses. They simply contain the commands for setting the output voltage according
to the specified pulse with delays in between.
Because the normal program which handles the user inputs is interrupt-based, the use of delays is the
simplest solution for defining the pulses.
When using delays, in theory the program cannot be aborted if the trigger button is pressed during the
generation of a cranking pulse. Therefore adding the command
if( stop_pulse() ) return;
each several hundred microseconds allows checking for trigger-button actuation during the generation of a
pulse. If trigger-button activation is detected, the command aborts generation of the pulse.
The output voltage can be changed by the VID interface between 1.99 V and 15.12 V. For lower or higher
voltages, change the resistors of the VID interface.
The VID interface has a width of 8 bits, which results in 256 steps (0 equals 1.99 V, 255 equals 15.12 V);
one step equals approximately 51.5 mV. One can calculate the decimal value for a specific output voltage,
6 V for example, using this formula:

To set the output voltage to 6 V, write a value of 78 into the register of the output port connected to the
VID interface using the command
VID_POUT = 78;
The VID_POUT definition is the output register of port 1 (P1OUT).
An Excel® sheet containing the precise calculations for all 256 steps and also examples for generating
sinusoidal waveforms is available on http://www.ti.com/tool/pmp7233.
The pulse.c file also contains three test functions, which are not used but show an easy method for
generating a rectangular, a saw tooth, and a sinusoidal waveform.
• void generate_pulse_test_mode_1(void) — Rectangular waveform
• void generate_pulse_test_mode_2(void) — Sawtooth waveform
• void generate_pulse_test_mode_3(void) — Sinusoidal waveform
4.2 Programming the Microcontroller
Debugging the program and flashing the microcontroller requires a debugger to connect the EVM with the
computer. One can either use the MSP430 USB Debugging Interface (MSP-FET430UIF) or the
inexpensive MSP430 LaunchPad (MSP-EXP430G2). Either option uses the Spy-Bi-Wire interface to save
pins on the microcontroller instead of using a true JTAG connection.

STANDARD TERMS AND CONDITIONS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, or
documentation (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance with the terms and conditions set forth herein.
Acceptance of the EVM is expressly subject to the following terms and conditions.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms and conditions that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms and conditions do not apply to Software. The warranty, if any, for Software is covered in the applicable Software
License Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for any defects that are caused by neglect, misuse or mistreatment
by an entity other than TI, including improper installation or testing, or for any EVMs that have been altered or modified in any
way by an entity other than TI. Moreover, TI shall not be liable for any defects that result from User's design, specifications or
instructions for such EVMs. Testing and other quality control techniques are used to the extent TI deems necessary or as
mandated by government requirements. TI does not test all parameters of each EVM.
2.3 If any EVM fails to conform to the warranty set forth above, TI's sole liability shall be at its option to repair or replace such EVM,
or credit User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the
warranty period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to
repair or replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall
be warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
3Regulatory Notices:
3.1 United States
3.1.1 Notice applicable to EVMs not FCC-Approved:
This kit is designed to allow product developers to evaluate electronic components, circuitry, or software associated with the kit
to determine whether to incorporate such items in a finished product and software developers to write software applications for
use with the end product. This kit is not a finished product and when assembled may not be resold or otherwise marketed unless
all required FCC equipment authorizations are first obtained. Operation is subject to the condition that this product not cause
harmful interference to licensed radio stations and that this product accept harmful interference. Unless the assembled kit is
designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit must operate under the authority of
an FCC license holder or must secure an experimental authorization under part 5 of this chapter.
3.1.2 For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant:
CAUTION
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
