the timeout period after MR goes high. Leave unconnected or connect to VDD when unused.
PFI

Power-fail input compares to 0.551 V with no additional delay. Connect to VDD if not used.
PFO
TPS3103

Active-low reset output. Either push-pull or open-drain output stage.
TPS3110
Active-low reset output. Logic level at RSTSENSE only depends on the voltage at SENSE and

TPS3106,
A reset will be asserted if the voltage at SENSE is lower than 0.551 V. Connect to VDD if

6
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.
