The MX16171 high-side OR-ing FET controller works with an external MOSFET and acts as an ideal diode rectifier when connected in series with the power supply. This OR-ing controller enables MOSFETs to replace diode rectifiers in power distribution networks, reducing power loss and voltage drop.
The MX16171 controller provides charge pump gate drive for an external N-channel MOSFET and fast response comparator to turn off the FET when current flows in reverse. The MX16171 can be connected to power supplies from 1V to 50V and can withstand transient voltages up to 60V.
