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), and window (OV&UV) conditions. TPS3762 device offers built-in hysteresis that provides noise immunity and maintains stable operation.

Although not required in most cases, for noisy applications good analog design practice is to place a 10 nF to 100 nF bypass capacitor at the SENSE inputs to reduce sensitivity to transient voltages on the monitored signal. SENSE can be connected directly to VDD pin.
