RESET1/RESET2 Outputs

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 TPS3760EVM is the TPS3760A012DYYR, which represents an undervoltage active-low open-drain output on RESET1 and is a single channel device. If using the EVM with another part in the TPS3760-Q1/TPS3760 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 J5 (pull-up to VDD for RESET1) or J6 (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 within the operating range by populating J5 on the middle and right pins for RESET1 and populating J6 on the middle and right pins for RESET2 and connecting a voltage to TP3 for RESET1 and a voltage to TP4 for RESET2.
