2.1 INPUT/OUTPUT CONNECTORS AND JUMPER DESCRIPTION
I_SEL selects the current consumption measurement method: Open, current consumption
measured with DMM connected between TP1 and VDD test points. 3-2 shorted, current
consumption = Voltage drop on R_SH divided by R_SH 1-2 R_SH bypass
IO 5-pin header connector to bring out MOS_DRV, TCAL, DONE, VDD_µC, and GND
signals.
S1 4 positions SPDT to set the D0, D1, D2 logic values and the source of PGOOD signal
(refer to Table 1)
Table 1. S1 Description
Description Slider position Value

In case the PGOOD is provided by an external power supply, set PG_SEL=1, Remove the REPG resistor
and connect a power supply to the EXT_PGOOD test point.
VCC 2- pin female connector to plug the TPL5100EVM into MSP430 launchpad.
RST 2- pin female connector to plug the TPL5100EVM into MSP430 launchpad.
J1_10 10-pin female connector to plug the TPL5100EVM into MSP430 launchpad.
J11_20 10-pin female connector to plug the TPL5100EVM into MSP430 launchpad.
SUPPLY test point to connect external supply voltage in alternative to the coin cell battery.
VDD test point to monitor VDD pin of TPL5100.
TP1 test point to monitor the external supply voltage or coin cell battery voltage.
EXT_PGOOD test point to connect external voltage supply for PGOOD signal.
GND test point of the ground, connect here the GND of the power supplies.
BT coin cell 2032 battery holder.
2.2 EVALUATION BOARD CONFIGURATION
The evaluation board can work standalone or plugged in to MSP430 launchpad, the following steps are in
common for both usages.
• Set the desired delay, configuring S1 (from position 2 to 4).
• Set the POWER GOOD source, configuring S1 (position 1), if you set external source connect the
voltage source between the EXT_PGOOD and GND test points; do not turn on this voltage source.
Refer to the data sheet regarding the allowable voltage range. This can be found on the MSP430
LaunchPad Wiki (MSP430 LaunchPad (MSP-EXP430G2) Wiki).
• Configure I_SEL as explained in Section 2.1.
• Plug the evaluation board into the launchpad according to Table 2
2.2.1 EVM Plugged into MSP430 Launchpad
• Load the code present in Section 5 of this User™s Guide, into the MSP430 of the launchpad. Refer to
the MSP430 launchpad documentation (MSP430 LaunchPad (MSP-EXP430G2) Wiki) for more details.
