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

EVALUATION BOARD CONFIGURATION
The evaluation board can work standalone or plugged into the MSP430 launchpad; the following steps
apply to both usages:
apply to 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 the 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 (
