NAME
FUNCTION
Open-Drain, Active-Low Reset Output. RESET asserts when any input voltage falls below its
1
1
RESET
undervoltage threshold or when MR is pulled low. RESET remains low for 200ms after all
assertion-causing conditions are cleared. An external pullup resister is required.
Open-Drain, Active-Low Watchdog Timer Output. Logic output for the watchdog timer function.

2
WDO
WDO goes low when WDI is not strobed high-to-low or low-to-high within the watchdog timeout
period.
Open-Drain Active-Low Overvoltage Output. OV asserts when any input voltage exceeds its

OV
overvoltage threshold. OV remains low for 25μs after all overvoltage conditions are cleared.
An external pullup resistor is required.
