NAME

PFI

PFO

RST

FUNCTION

Power-Fail Voltage

Monitor Input. High-

impedance input for

internal power-fail monitor

comparator. Connect PFI

to an external resistor-

divider network to set the

power-fail threshold

voltage (0.626V typical

internal reference

voltage). Connect to GND,

VCC1, or VCC2 if not used.

Active-Low Power-Fail

Monitor Output, Open-

Drain or Push-Pull. PFO is

asserted low when PFI is

less than 0.626V. PFO

deasserts without a reset

timeout period. Open-

drain outputs require an

external pullup resistor.

Push-pull outputs are

referenced to VCC1.

Active-High Reset Output,

Open-Drain or Push-Pull.

RST changes from low to

high when VCC1 or VCC2

drops below selected

reset thresholds, RSTIN is

below threshold, MR is

pulled low, or the

watchdog triggers a reset.

RST remains HIGH for the

reset timeout period after

VCC1/VCC2/RSTIN exceed

the device reset

thresholds, MR goes low

to high, or the watchdog

triggers a reset. Open-

drain outputs require an

external pullup resistor.

Push-pull outputs are

referenced to VCC1.
