Manual-reset input. Pull low to force a reset. RESET remains low as long as MR is low and for
the timeout period after MR goes high. Leave unconnected or connect to V
DD
when unused.
Power-fail input compares to 0.551 V with no additional delay. Connect to V
DD
if not used.
Power-fail output. Goes high when voltage at PFI rises above 0.551 V.

Active-low reset output. Either push-pull or open-drain output stage.
Active-low reset output. Logic level at RSTSENSE only depends on the voltage at SENSE and
the status of MR.
Active-low reset output. Logic level at RSTVDD only depends on the voltage at V
DD
and the
status of MR.
A reset will be asserted if the voltage at SENSE is lower than 0.551 V. Connect to V
DD
if
unused.
Supply voltage. Powers the device and monitors its own voltage.
Watchdog timer input. If WDI remains high or low longer than the time-out period, then reset is
triggered. The timer clears when reset is asserted or when WDI sees a rising edge or a falling
edge.
