A. For open-drain output option, the timing diagram assumes the RESETx_UVOD / RESETx_UVOD pin is connected via an external pull-up resistor to VDD.
B. 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.
C. RESETx_UVxx / RESETx_UVxx is asserted when VDD goes below the UVLO(MIN) threshold after the time delay, tCTRx, is reached.
