The SENSE1 and SENSE2 inputs allow for any voltage rails to be monitored divided down through resistors. The default option of the TPS37AQ1EVM is populated with a TPS37A010122DSKRQ1 device, which has adjustable 0.8V thresholds. The resistors R4 and R6 (both 49.9kΩ) control the voltage divider for SENSE1. The resistors R5 and R7 (both 49.9kΩ) control the voltage divider for SENSE2. These 0603 resistors can be replaced with any values to form a voltage divider that can then divide down to trip at the 0.8V threshold. This behavior and instructions on selecting these resistors can be found described in the TPS37A-Q1 datasheet in the 'Adjustable Voltage Thresholds' section. To use the voltage divider located on-board, make sure to populate a jumper on J5 (shorting the first two pins) for SENSE1 and J6 (shorting the first two pins) for SENSE2 and connect the desired voltage rails to the header J1 for SENSE1 and J2 for SENSE2. Conversely, to monitor VDD on either SENSE1 or SENSE2 or both, populate a jumper on J5 (shorting the second two pins) for SENSE1 and J6 (shorting the second two pins) for SENSE2. If you wish to operate SENSE1 and SENSE2 as one input, you can tie these two together by populating a jumper on J11. The adjustable delays on the sense inputs can be found detailed in Section 4.5.
