The ISL6146 represents a family of OR-ing MOSFET controllers capable of OR-ing voltages from 1V to 18V. Together with suitably sized N-channel power MOSFETs, the ISL6146 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.
