TWL6032 Evaluation Module (EVM) User’s Guide
1 Introduction
1.1 Description
1.1.1 Device Description
The TWL6032 device is an integrated power-management integrated circuit (PMIC) for applications
powered by a rechargeable battery. The device provides five configurable step-down converters with up to
5-A current capability for memory, processor core, I/O, auxiliary, preregulation for low drop-out voltage
regulators (LDOs), and so forth. The TWL6032 device also contains nine LDOs for external use that can
be supplied from a battery or a preregulated supply. The power-up and power-down controller is
configurable and can support any power-up and power-down sequence (programmed in OTP memory).
The real-time clock (RTC) provides three 32-kHz clock outputs, seconds, minutes, hours, day, month, and
year information, as well as alarm wakeup and timer. The TWL6032 device supports 32-kHz clock
generation based on a crystal oscillator.
The TWL6032 device integrates a switched-mode system supply regulator from a universal serial bus
(USB) connector. The TWL6032 includes power paths from the USB and battery with supplemental mode
for immediate startup, even with an empty battery. The battery switch uses an external low-Ωic PMOS
transistor allowing minimal serial resistance during fast charging and when operating from a battery. The
TWL6032 device can also be used without the external PMOS transistor; the battery is then always tied to
the system supply and the switched-mode regulator is used for battery charging.
Project collateral and source code discussed in this application report can be downloaded from the
following URL: http://www.ti.com/lit/zip/SWCU105.
1.1.2 EVM Kit Description
The TWL6032 evaluation module (EVM) is a stand-alone module that demonstrates the functions of the
integrated PMIC. The EVM uses a USB cable and an MSP430™ device (mounted on the EVM) to control
the standard inter-integrated circuit (I2C™) interfaces in the TWL6032 device. It includes Windows®-
compatible software to interface with the device. The software is a simple graphical user interface (GUI)
that simplifies registers access for the IC.
1.1.3 EPROM Power-Up Sequence Description
This user's guide is common for all TWL6032x parts. The only difference in these parts is the EPROM
sequence for power up. Each part has a unique EPROM sequence to satisfy the attached application
processor. For details of the EPROM sequence, see the corresponding user's guide in the Application
Notes section on the TWL6032x product page.

6.6 Install GUI
The GUI accompanying this device is simple and runs on a Windows PC. Ensure that your machine
supports Microsoft .NET Framework 3.5.
6.6.1 Installation Instructions
To install the GUI perform the following steps:
1. Unzip the installable file, SWCC013.zip.
2. Create a new folder or unzip it into any appropriate windows folder. By default, the GUI is installed in
C:\Program Files\Texas Instruments\TWL6032EVM.
3. Open the GUI by clicking the Setup.exe icon in the folder created in Step 2. The GUI can also be
opened by clicking:
Start → All Programs → Texas Instruments → TWL6032
Two files are generated: MSP Firmware upgrade utility and TWL6032 EVM
6.6.2 GUI Files
The GUI software consists of the following files:
• .dll
• .exe
• .xml
The .xml file is the main file that contains all the device registers. The registers in this file are categorized
in blocks according to the functions. The .xml file also specifies the slave I2C address for the device.

7 Test Procedure
7.1 EVM Wakeup
For the first time, the MSP430 firmware must be flashed as follows:
1. Set jumper configuration as described in Table 1 and Table 2.
2. Plug the USB cable into the PC to flash the MSP430 on the board.
3. Load the MSP flash tool on the PC.
4. Click on MSP430 firmware upgrade utility.
5. Click the Next button.
6. Plug the USB cable into the connector on the board.
(a) Press the browse button then select USB2ANY and hit open
(b) The Upgrade button should be highlighted
7. Press the Upgrade button.
8. Wait for the MSP430 to be flashed.
9. Close the tool, then disconnect and reconnect the USB cable. The LED should blink three times then
stay on.
10. If a voltage source is used instead of a battery, the source must be able to sink some current.
7.2 Set Input Voltage
With the input supply off or disconnected from the unit under test, adjust the input voltage to 3.8 V. For the
supply connections, see Section 6.1, Input Supply. Ensure that the input power supply current limit is set
at 2 A.
7.3 Enable DUT
With the power supply connected to the input pins, turn on the power supply.
To power up the UUT, press the POWERON pin for 1 second. Check the following power outputs on the
EVM to check if the UUT powered on properly.

7.4 Power Consumption Test
When the device is powered on, the supply should show the power consumption in the range of 750 µA to
1.2 mA.
7.5 32-kHz Clock Test
Probe TP20 to check the clock. This should measure a 32-kHz clock.
7.6 Load Test
Turn on the electronic loads (see Section 6.3, Load). When the DC-DCs (VDD1, VDD2, and VIO) are
loaded, they should regulate at the same voltage as shown in Table 13.
7.7 Test Complete
Turn off the power supply and remove all connections from the UUT.
7.8 Final Jumper Connections
Leave the jumper connections as done above for the test setup.
7.9 Load Test
7.9.1 GUI Test
Connecting the GUI to the EVM:
If the board is powered on, turn it off. Turn on the EVM supply and power on the board and open the GUI.
The GUI can be controlled from a PC or laptop. The cable is connected between the PC or laptop USB
slot and connector J8 on the TWL6032 EVM.
Once the GUI is connected to the EVM, the device registers can be written. In the Registers section of the
GUI, scroll down to the SMPSx_CFG_FORCE register. Write the values listed in Table 14 to the registers.
