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.

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 <0.3µs Response

Time to Dead Shorts on Sourcing Supply. HS Comparator

also has Resistor-adjustable Trip Level

• HR Amplifier allows Quiet, <100µs MOSFET Turn-off for

Power Supply Slow Shut Down
