IN1
Input Voltage 1. See Selector Guide for monitored voltages.
2—
IN2
Input Voltage 2. See Selector Guide for monitored voltages.
3—
IN3
Input Voltage 3. See Selector Guide for monitored voltages.
4—
IN4
Input Voltage 4. See Selector Guide for monitored voltages.

6—
PWRGD4
Output 4. PWRGD4 asserts low when IN4 falls below its threshold voltage. PWRGD4 is open
drain with a 10A internal pullup current source to VCC.
7—
PWRGD3
Output 3. PWRGD3 asserts low when IN3 falls below its threshold voltage. PWRGD3 is open
drain with a 10A internal pullup current source to VCC.
8—
PWRGD2
Output 2. PWRGD2 asserts low when IN2 falls below its threshold voltage. PWRGD2 is open
drain with a 10A internal pullup current source to VCC.
9—
PWRGD1
Output 1. PWRGD1 asserts low when IN1 falls below its threshold voltage. PWRGD1 is open
drain with a 10A internal pullup current source to VCC.

VCC
Power-Supply Input. Connect VCC to a 2.0V to 5.5V supply. An undervoltage lockout circuit
forces all PWRGD_ outputs low when VCC drops below the minimum operating voltage. VCC
is not a monitored voltage for the MAX6709. For the MAX6714, RESET asserts low when VCC
drops below its threshold.
—1
MR
Manual Reset Input. Force MR low to assert the RESET output. RESET remains asserted for
the reset timeout period after MR goes high. MR is internally pulled up to VCC.
—2
PFI1
Power-Fail Input 1. Input to noninverting input of the power-fail comparator. PFI1 is
compared to an internal 0.62V reference. Use an external resistor-divider network to adjust
the monitor threshold.
—3
PFI2
Power-Fail Input 2. Input to noninverting input of the power-fail comparator. PFI2 is
compared to an internal 0.62V reference. Use an external resistor-divider network to adjust
the monitor threshold.
—4
PFI3
Power-Fail Input 3. Input to noninverting input of the power-fail comparator. PFI3 is
compared to an internal 0.62V reference. Use an external resistor-divider network to adjust
the monitor threshold.
—6
PFO3
Power-Fail Output 3. PFO3 is an active-low, open-drain output with a 10A internal pullup to
VCC. PFO3 asserts low when PFI3 is below the selected threshold.
—7
PFO2
Power-Fail Output 2. PFO2 is an active-low, open-drain output with a 10A internal pullup to
VCC. PFO2 asserts low when PFI2 is below the selected threshold.
—8
PFO1
Power-Fail Output 1. PFO1 is an active-low, open-drain output with a 10A internal pullup to
VCC. PFO1 asserts low when PFI1 is below the selected threshold.
—9
RESET
Reset Output. RESET is an active-low, open-drain output that asserts low when VCC drops
below its preset threshold voltage or when a manual reset is initiated. RESET remains low for
the reset timeout period after VCC exceeds the selected reset threshold or MR is released.
