The RESET1 and RESET2 outputs on the device represent the effect of the voltage monitoring after operating on the inputs SENSE1 and SENSE2, respectively. The device on the TPS37AQ1EVM is the TPS37A010122DSKRQ1, which represents an overvoltage active-low open-drain output on RESET1 and an undervoltage active-low open-drain output on RESET2. If using the EVM with another part in the TPS37x-Q1/TPS38x-Q1 family, adjustments need to be made to the default configuration to the EVM. For parts that use a push-pull topology instead of open-drain, you should depopulate the jumpers on J3 (pull-up to VDD for RESET1) or J4 (pull-up to VDD for RESET2). Additionally, if you want to use a different sized pull-up resistor on the reset pullups, either 10.0kΩ resistor at R2 or R3 can be replaced with another 0603 resistor. The RESET1 and RESET2 outputs can be pulled up to any voltage by depopulating the jumper on J3/J4 and connecting the top pin of the headers to any voltage lower than VDD.
