8.3.7 RESET Latch Mode

The TPS3760 features a output latch mode on the RESET/RESET pin when connecting the LATCH pin to common ground. A pull-down resistor, 10 kΩ, is recommended to limit current consumption of the system. In latch mode, if the RESET/RESET pin is low or triggers low and less than 1.4V is applied to the LATCH pin, the RESET/RESET pin stays asserted regardless if VSENSE goes within the acceptable voltage boundaries (VSENSE > VITP + Vhyst for UV or VSENSE < VITN - Vhyst for OV). To unlatch the device a voltage greater than 2.1 V for greater than 3 μs is applied to the LATCH pin. This is recommended to maintain a proper unlatch. The RESET/RESET pin triggers high after the duration of tctr. TI recommends using a series resistance to limit current when an unlatch voltage is applied.
