NAME
RSTIN
WDI
PFI
Watchdog Input. If WDI
remains high or low for
longer than the watchdog
timeout period, the
internal watchdog timer
runs out and the reset
output asserts for the
reset timeout period. The
internal watchdog timer
clears whenever a reset
is asserted or WDI sees a
rising or falling edge. The
watchdog has a long
timeout period (35s min)
after each reset event
and a short timeout
period (1.12s min) after
the first valid WDI
transition.
Undervoltage Reset
Comparator Input. High-
impedance input for
adjustable reset monitor.
The reset output is
asserted when RSTIN falls
below the 0.626V internal
reference voltage. Set the
monitored voltage reset
threshold with an external
resistor-divider network.
Connect RSTIN to V
V
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
not used.
CC
2 if not used.
