NAME
FUNCTION
Watchdog Input. If WDI remains high or low for longer than the watchdog timeout

period, the internal watchdog timer expires, and a reset is triggered for the reset
timeout period. The internal watchdog timer clears whenever reset is asserted,
the manual reset is asserted, or WDI sees a rising or falling edge.

remains asserted while MR is held low and for the reset timeout period after MR
transitions high. Leave MR unconnected or connect to V CC if unused. MR is
internally pulled up to V CC through 10k ? .
Active-Low Open-Drain or Push-Pull Reset Output. RESET transitions from high to
low when V CC drops below the selected reset threshold, MR is pulled low, or the

watchdog timer expires. RESET remains low for the reset timeout period after
V CC exceeds the device reset threshold, MR deasserts, or after the watchdog
timer expires. Push-pull RESET outputs are referenced to V CC . Open-drain
RESET outputs require an external pullup resistor.

Supply Voltage. Input for V CC reset monitor. For noisy systems, bypass V CC with
a 0.1μF capacitor to GND.
Active-High Push-Pull Reset Output. RESET transitions from low to high when
V CC drops below the selected reset threshold, MR is pulled low, or the watchdog

timer expires. RESET remains high for the reset timeout period after V CC
exceeds the device reset threshold, MR deasserts, or after the watchdog timer
expires. RESET is referenced to V CC .
