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 (V
IT
(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 V
DD
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.

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.
NOTE 1: 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.
