The Renesas Low Voltage OR-ing FET Controller is a family of OR-ing MOSFET controllers capable of OR-ing voltages from 1V to 18V. Together with suitably sized N-channel power MOSFETs it increases power distribution efficiency when replacing a power OR-ing diode in high current applications. It provides gate drive voltage for the MOSFET(s) with a fully integrated charge pump.

VIN hot swap transient protection rating to +24V
High speed comparator provides fast <0.3μs turn-off in response to shorts on sourcing supply
Fastest reverse current fault isolation with 6A turn-off current
Very smooth switching transition
Internal charge pump to drive N-channel MOSFET
User programmable VIN - VOUT Vth for noise immunity
