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
• Open Drain, Active Low Fault Output with 120µs Delay
• Provided in Packages Compliant to UL60950 (UL1950)
   Creepage Requirements
• QFN Package:
   - Compliant to JEDEC PUB95 MO-220
      QFN - Quad Flat No Leads - Package Outline
   - Near Chip Scale Package footprint, which improves
      PCB efficiency and has a thinner profile
• Pb-Free (RoHS Compliant)

Applications
• ORing MOSFET Control in Power Distribution Systems
• N + 1 Redundant Distributed Power Systems
• File and Network Servers (12V and 48V)
• Telecom/Datacom Systems
