NAME
PFO
RST
PFI
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,
V
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 V
Active-High Reset Output,
Open-Drain or Push-Pull.
RST changes from low to
high when V
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
V
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 V
