NAME

FUNCTION

Power-Fail Voltage

Monitor Input. High-

impedance input for

internal power-fail monitor

comparator. Connect PFI

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

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

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.
