LT4351 Datasheet - Linear Technology

LT4351 MOSFET Diode-OR Controller

The LT®4351 creates a near ideal diode using external single or back-to-back N-channel MOSFETs. This ideal diode function permits low loss ORing of multiple power sources. Power sources can easily be ORed together to increase total system power and reliability with minimal effect on supply voltage o.
