Wuxi Maxinmicro MX5050T

The MX5050T 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 MX5050T 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 MX5050T can be connected to power supplies from 1V to 40V （a separate VS supply is needed when IN is 1V to 4V）and can withstand transient voltages up to 60V.
