Input Voltage 1. See the Selector Guide for monitored voltages.
Input Voltage 2. See the Selector Guide for monitored voltages. IN2 is the power-supply input for
the device.
Input Voltage 3. See the Selector Guide for monitored voltages.
Input Voltage 4. See the Selector Guide for monitored voltages.
Ground
Reset Output, Active Low. RESET goes low when any input goes below its specified threshold. After
all inputs are above their threshold voltage, RESET remains low for at least 140ms (minimum) before
going high. RESET output is open drain with a weak internal pullup to IN2.
