7.3.2 SENSE

The SENSE pin connects to the supply rail that is to be monitored. The sense pin on each device is configured to monitor either overvoltage (OV), undervoltage (UV), or window (OV and UV) conditions. TPS3710x-Q1 device offers built-in hysteresis that provides noise immunity and maintains stable operation.

Although not required in most cases, designers can use either tCTS or place a 10nF to 100nF bypass capacitor at the SENSE input to reduce sensitivity to transient voltages on the monitored signal. SENSE can be connected directly to VDD pin.
