Data Sheet October 6, 2011 ISL6144 FN9131.7 High Voltage ORing MOSFET Controller The ISL6144 ORing MOSFET Controller and a suitably sized N-Channel power MOSFET(s) increases power distribution efficiency and availability when replacing a power ORing diode in high current applications. In a multiple supply, fault tolerant, redundant power distribution system, paralleled similar power supplies contribute equally to the load current through various power sharing schemes. Regardless of the scheme.

ISL644 Features

* Wide Supply Voltage Range +9V to +75V

* Transient Rating to +100V

* Reverse Current Fault Isolation

* Internal Charge Pump Allows the use of N-Channel MOSFET

* HS Comparator Provides Very Fast
