FUNCTION
Input Voltage 1. See
Selector Guide
for monitored voltages.
Input Voltage 2. See
Selector Guide
for monitored voltages. IN2 is the power-supply input for the
device. V
CC
is the power-supply input for the device and is not a monitored voltage (MAX6710Q only).
Input Voltage 3. See
Selector Guide
for monitored voltages.
Input Voltage 4. See
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, V
CC
.
