For open-drain output option, the timing diagram assumes the RESETx_OVOD / RESETx_OVOD pin is connected via an external pull-up resistor to VDD.

Be advised that this diagram shows the VDD falling slew rate is slow or the VDD decay time is much larger than the propagation detect delay (tCTRx) time.

RESETx_OVxx / RESETx_OVxx is asserted when VDD goes below the UVLO(MIN) threshold after the time delay, tCTRx, is reached.
