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 V
CC
is below the UVLO threshold and remains low for 140ms (min) after
V
CC
exceeds the UVLO threshold.

GND
N.C.
Ground
No Connection. Leave unconnected or connect to V
CC
.
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.
