NAME
FUNCTION
1
WDO
Active-Low Watchdog Output. Pulses low for 140ms (min) when the watchdog timer exceeds the watchdog
timeout period. WDO is low when VCC is below the UVLO threshold and remains low for 140ms (min) after
VCC exceeds the UVLO threshold.

GND
Ground
3
N.C.
No Connection. Leave unconnected or connect to VCC.
4
WDI
Watchdog Input. If WDI remains either high or low for longer than the watchdog timeout period, the internal
watchdog timer runs out and a watchdog pulse period is triggered. The internal watchdog timer clears
whenever a watchdog pulse period is asserted, or whenever WDI sees a rising or falling edge. If WDI is left
unconnected or is connected to a three-stated buffer output, the watchdog is disabled.
