NAME
FUNCTION
11
RESET
Open-Drain, Active-Low Reset Output. RESET asserts when any input voltage falls below its
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.
22
WDO
Open-Drain, Active-Low Watchdog Timer Output. Logic output for the watchdog timer function.
WDO goes low when WDI is not strobed high-to-low or low-to-high within the watchdog timeout
period.
33
OV
Open-Drain Active-Low Overvoltage Output. OV asserts when any input voltage exceeds its
overvoltage threshold. OV remains low for 25s after all overvoltage conditions are cleared.
An external pullup resistor is required.
4
GND
Ground
Typical Operating Characteristics (continued)
(VIN1–VIN4 or VCC = 5V, WDI = GND, MARGIN = MR = BP, TA = +25°C, unless otherwise noted.)
