10 / 22 page TPS31xxExx, TPS31xxH20, TPS31xxK33 ULTRALOW SUPPLY CURRENT/SUPPLY VOLTAGE SUPERVISORY CIRCUITS SLVS363B − AUGUST 2001 − REVISED SEPTEMBER 2004 www.ti.com 10 SENSE The voltage at the SENSE input is compared with a reference voltage of 0.551 V. If the voltage at SENSE falls below the sense-threshold (VIT−(S)), reset is asserted. On the TPS3106, a dedicated RSTSENSE output is available. On the TPS3110, 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 15 mV of hysteresis. For proper operation of the SENSE-comparator, the supply voltage must be higher than 0.8 V.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to GND. For reliable operation, the device must not be operated at 3.6 V for more than t=1000h continuously.
