FUNCTION
Supply Input. Bypass with a 0.1µF capacitor to
GND.
Monitoring Input. Connect IN to its nominal input voltage.
When V_IN falls outside overvoltage/undervoltage window
threshold, RESET asserts.
No Connect. Leave open or connect to ground.
Ground
Active-Low, Open-Drain Reset Output. RESET
asserts when V_IN falls outside of the undervoltage/
overvoltage window threshold. RESET stays
asserted for the reset timeout period after V_IN fall
within the undervoltage/overvoltage window threshold.
RESET requires a pullup resistor.
Monitoring Input 1. Connect IN1 to its nominal input
voltage. When V_IN1 falls outside undervoltage/
overvoltage window threshold, RESET1 asserts.
For the quad input (MAX16135), RESET1 asserts
when either IN1 and/or IN2 falls outside the
undervoltage/overvotlage window threshold.
Monitoring Input 2. Connect IN2 to its nominal input
voltage. When V_IN2 falls outside the undervoltage/
overvoltage window threshold, RESET2 asserts.
For the quad input (MAX16135), RESET1 asserts
when either IN2 and/or IN1 falls outside the
undervoltage/overvotlage window threshold.
Active-Low, Open-Drain Reset Output 2. RESET2
asserts when V_IN2 falls outside the undervoltage/
overvoltage window threshold. RESET2 stays
asserted for the reset timeout period after V_IN2
falls within the undervoltage/overvoltage window
threshold. RESET2 requires a pullup resistor. For
the MAX16135, RESET2 asserts when either IN3
and/or IN4 falls outside the undervoltage/
overvoltlage window threshold.
Active-Low, Open-Drain Reset Output 1. RESET1
asserts when V_IN1 falls outside the undervoltage/
overvoltage window threshold. RESET1 stays
asserted for the reset timeout period after V_IN1
falls within the undervoltage/overvoltage window
threshold. RESET1 requires a pull up resistor.For
the MAX16135, RESET1 asserts when either IN1
and/or IN2 falls outside the undervoltage/overvot-
lage window threshold.
