FUNCTION
Negative Terminal of External Flying Charge-Pump Capacitor
Positive Terminal of External Flying Charge-Pump Capacitor
Open-Drain Active-Low Output. OVP sinks up to 10mA when V OVI ≥ 0.6V and V IN ≥ V BUS . OVP can be
used to drive an optodiode. Cycle power or pull UVLO low and then high to reset OVP.
Open-Drain Active-Low Output. PGOOD pulls low when V UVLO ≤ 0.6V or V OVI ≥ 0.6V.
ORing MOSFET Slow-Comparator Reverse Voltage Threshold and Blanking Time Setting Input. Connect
a resistor from STH to GND to set the threshold. Connect a capacitor from STH to GND to set the
blanking time. Leave STH floating to set the internal threshold (-12mV) and internal blanking time
(0.9ms).
Fast-Comparator Reverse Threshold Setting. Connect a resistor from FTH to GND to set the fast-
comparator reverse voltage threshold from -24mV to -400mV.
Overvoltage Comparator Input. Connect OVI to BUS through a resistive divider.
Undervoltage Lockout Comparator Input. Connect UVLO to IN through a resistive divider. The MAX5079
remains off until V UVLO rises above 0.66V. When V UVLO rises above 0.664V, V GATE is raised to V IN .
Power Ground. Ground discharge path of the 2A GATE pulldown. Connect to external power ground
plane.
Gate-Driver Output for n-Channel ORing MOSFET
Bus Voltage-Sense Input. Connect BUS to the drain of the ORing MOSFET to sense the polarity of the
Bus Current. The MAX5079 receives its power from BUS when V IN and V AUXIN are not present.
Signal Ground. Connect to the low-level signal or analog ground.
Source Connection for ORing MOSFET and Supply Input for the MAX5079. Connect IN directly to the
power-supply voltage of 2.75V to 13.2V or 1V to 13.2V with V AUXIN ≥ 2.75V.
Auxiliary Power-Supply Input. AUXIN supplies power to the IC when 1V ≤ V IN ≤ 2.75V. Connect AUXIN to
2.75V or higher if V IN is less than 2.75V.
