7.3.4 SENSE

The voltage at the SENSE input is compared with a reference voltage of 0.551V. If the voltage at SENSE falls below the sense-threshold (VIT − (S)), reset is asserted. On the TPS3106 device, a dedicated RSTSENSE output is available. On the TPS3110 device, the logic signal from SENSE is OR-wired with the logic signal from VDD or MR. An internal timer delays the return of the output to the inactive state, once the voltage at SENSE goes above 0.551 V plus about 15mV of hysteresis. For proper operation of the SENSE-comparator, the supply voltage must be higher than 0.8V.
