Cautions and Warnings
Warning! Do not leave EVM powered when unattended.
Warning Hot Surface! Contact may cause burns. Do not touch. Please take the proper precautions when
operating.
1 Getting Started
The DRV2511Q1EVM provides an evaluation of platform for different solenoids and driving waveforms. It
can also be used as a demonstration board allowing access to both the MSP430 and DRV2511-Q1
through multiple test points. Input type can be controlled using the Haptics Control Console for the
DRV2511Q1EVM. The input is generated by an MSP430F5510 by using PWM signals. The EVM also has
the option for the DRV2511-Q1 to receive inputs externally through the jumpers available on the board if
necessary. Figure 2 below is the block diagram:

1.1 Powering the Board
To power the board, connect the DRV2511Q1EVM to an available USB port on your computer using the
included Micro-USB cable. When USB power is applied, the TL760M33Q will take the 5-V supply voltage
down to a regulated 3.3 V. The green 3.3-V LED will turn on and the MSP430 will be powered on. To
power the DRV2511-Q1, external power must be supplied through header J5. The driver will power on
when the external power supply provides at least 4.5 V.
1.2 Quick Start Board Setup
The DRV2511Q1EVM comes preprogrammed to use with Haptics Control Console. Figure 3 below is a
screenshot of Haptics Control Console:
Figure 3. Haptics Control Console
1. Out of the box, the on-board MSP430 is set to receive commands from Haptics Control Console
through the USB.
2. Use the included Micro-USB cable to connect the DRV2511Q1EVM board to an available USB port on
a computer. The green 3.3-V LED will turn on and the MSP430 will be powered.
3. Once the latest version of Haptics Control Console has opened, and the device is connected to your
computer, you will see that the USB tab will read out '0.TI DRV2511Q1 EVM v1.[version]'. When
Haptics Control Console has recognized the DRV2511Q1EVM, press 'Connect' to access the device
Console window.

1.3 Configuring the Input
Out of the box, the jumpers are set to connect a USB cable for microcontroller power, and drive the
DRV2511-Q1 inputs from an MSP430 through a 2nd order low pass filter. Table 1 shows the summary of
the possible configurations for the input signal:
Table 1. Input Jumper Configurations
Jumper Default Position Description
J9 Open (+) bypass 2nd order filter (When Shorted)
J6 Open (–) bypass 2nd order filter (When Shorted)
J10 Short Pin 1-2 (+) PWM from MSP430
J8 Short Pin 1-2 (–) PWM from MSP430
Figure 4. Input 2nd Order Filter
As seen above in Figure 4, J9 & J6 provide the user the option to filter the input signal (IN+ or IN-) coming
from either the MSP430 or external source. If an external input is used, remove the jumper that is
connected to the MSP430 (Pin 1 on J10 & J8) in order to avoid potential damage to the MCU.
When using an external input, the 2nd order filter is utilized by connecting the input signal to Pin 2 of J10
& J8 (assuming J9 and J6 are open). To bypass the 2nd order filter, connect the external input signal
directly to Pin 2 of J9 & J6, or connect the external input signal to Pin 2 of J10 & J8, and short jumpers J9
and J6.
1.4 1.4 Connecting a Load
To begin, caution is advised as the DRV2511-Q1 is a high-current device that can provide up to 8 A of
output current drive. Also, solenoids can become hot after extended use. Be conscious of the current and
temperature ratings of the solenoid, as application of pulses and waveforms for an extended period can
cause damage to the solenoids.
1. With the power supply off, connect either ± terminals on header J7 of the DRV2511Q1EVM to the
solenoid. Polarity only matters if you are using a polarized solenoid. Typical solenoids are not
polarized.

MSP430.
2.4 Haptics Control Console
Haptics Control Console allows the user to control the inputs to the DRV2511-Q1 using the on-board
MSP430. The user can also control the DRV2511-Q1 enable pin, standby pin, and output switching
frequency.
As seen in Figure 5 below, the console contains a set of controls to manipulate the PWM Input Frequency,
PWM Voltage Percentage, and duration of the PWM signal.

manually entering a frequency value. The minimum frequency is 1 Hz and the maximum frequency can be
up to 65 kHz. The optimum frequency for solenoid operation is less than 200 Hz.
2.4.2 PWM Voltage Percentage
PWM Voltage Percentage selects the max input range to the DRV2511-Q1. The full scale output voltage
of the MSP430 is in the range of 3.3 V.

2.4.3 PWM Signal Control
Located below the input Enable/Disable on the bottom right of Figure 5, the user has the ability to select
duration of the PWM input signal coming from the MSP430. The PWM signal can be driven continuously,
in pulses (with control of on and off time), or with a single pulse (with control of the pulse duration). The
control mode can be changed by clicking on the "continuous" button that will dynamically change to the
type of signal control selected.
2.4.4 Settings
In the settings section, the user can control the internal oscillator frequency, enable pin, and Hi-Z pin. To
operate the device be sure to have the enable pin high and Hi-Z pin low.

3.3 PWM, Analog and Single-Ended Inputs
By default, the DRV2511Q1EVM uses the MSP430 PWM input mode with a 2nd order low-pass filter. This
section describes each input mode and the modifications necessary for operation of each.
The DRV2511Q1EVM supports two input modes for driving the DRV2511-Q1:
• PWM input using MSP430: In this mode, the onboard MSP430 generates a PWM waveform that is
sent through the 2nd order low-pass input filter to the DRV2511-Q1.
• External analog input: An external source supplies an analog waveform to the INPUT header. The low-
pass input filter can be bypassed as described in Section 1.3.
– Single Ended Inputs: Connect the external analog input to either Pin 2 of J8 or J10. Refer to
Section 1.3 for more detailed input configuration.
– Differential Input: Connect the external analog inputs across J8 and J10 using Pin 2 on each
jumper. Refer to Section 1.3 for more detailed input configuration.
3.4 Gain Setting and Master / Slave
The gain of the DRV2511-Q1 is set by the voltage divider connected to the GAIN control pin. An internal
ADC is used to detect the four input states. The four states set the DRV2511-Q1 with gains of 20 dB, 26
dB, 32 dB, and 36 dB respectively. The gain setting is latched during power-up and cannot be changed
while the device is powered. Table 4 shows the recommended resistor values for each mode and gain
combination:
(1) Resistor tolerance should be 5% or better.
(2) R40 resistor is 0603
(3) R41 resistor is 0805
Table 4. Gain Settings

26 dB 100 kΩ20 kΩ30 kΩ
32 dB 100 kΩ39 kΩ15 kΩ
36 dB 75 kΩ47 kΩ9 kΩ
4 Measurement and Analysis
The DRV2511-Q1 uses PWM modulation to create the output signal for both solenoids and voice coils. To
measure the output signals, connect an oscilloscope or other measurement equipment to the filtered
output test points, “OUT+” and “OUT-”.
Figure 6. Terminal Blocks and Test Points
The DRV2511-Q1 PWM modulation frequency is set by default at 400 kHz. Solenoids and voice coils do
not operate at this high of frequencies and will only be affected by the modulated output waveform. For
measurement purposes, the output waveform needs to pass through a low-pass filter with a cutoff
frequency around 3.38 kHz. If the DRV2511Q1EVM filter is not used, TI recommends using a first-order,
low-pass filter with a cutoff between 1 kHz and 3.5 kHz.
