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
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
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
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
Power-Supply Input. Connect V
forces all PWRGD_ outputs low when V
is not a monitored voltage for the MAX6709. For the MAX6714, RESET asserts low when V
drops below its threshold.
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
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.
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.
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.
Power-Fail Output 3. PFO3 is an active-low, open-drain output with a 10µA internal pullup to
V
Power-Fail Output 2. PFO2 is an active-low, open-drain output with a 10µA internal pullup to
V
Power-Fail Output 1. PFO1 is an active-low, open-drain output with a 10µA internal pullup to
V
Reset Output. RESET is an active-low, open-drain output that asserts low when V
below its preset threshold voltage or when a manual reset is initiated. RESET remains low for
the reset timeout period after V
