Output 4. PWRGD4 asserts low when IN4 falls below its threshold voltage. PWRGD4 is open
drain with a 10μA internal pullup current source to V CC .
Output 3. PWRGD3 asserts low when IN3 falls below its threshold voltage. PWRGD3 is open
drain with a 10μA internal pullup current source to V CC .
Output 2. PWRGD2 asserts low when IN2 falls below its threshold voltage. PWRGD2 is open
drain with a 10μA internal pullup current source to V CC .
Output 1. PWRGD1 asserts low when IN1 falls below its threshold voltage. PWRGD1 is open
drain with a 10μA internal pullup current source to V CC .
Power-Supply Input. Connect V CC to a 2.0V to 5.5V supply. An undervoltage lockout circuit

V CC
forces all PWRGD_ outputs low when V CC drops below the minimum operating voltage. V CC
is not a monitored voltage for the MAX6709. For the MAX6714, RESET asserts low when V CC
drops below its threshold.

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 V CC .

Power-Fail Output 3. PFO3 is an active-low, open-drain output with a 10μA internal pullup to
V CC . PFO3 asserts low when PFI3 is below the selected threshold.
Power-Fail Output 2. PFO2 is an active-low, open-drain output with a 10μA internal pullup to
V CC . PFO2 asserts low when PFI2 is below the selected threshold.
Power-Fail Output 1. PFO1 is an active-low, open-drain output with a 10μA internal pullup to
V CC . PFO1 asserts low when PFI1 is below the selected threshold.
Reset Output. RESET is an active-low, open-drain output that asserts low when V CC drops
