Renesas | ISL6144IVZA

The ISL6144IVZA is a 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.

This can be used in 9 V to 75 V systems having similar power sources and has an internal charge pump to provide a floating gate drive for the N-Channel ORing MOSFET.

Features:

• Wide Supply Voltage Range +9 V to +75 V
• Transient Rating to +100V
• Reverse Current Fault Isolation
• Internal Charge Pump Allows the use of N-Channel MOSFET
• HS Comparator Provides Very Fast <0.3 µs Response Time to Dead Shorts on Sourcing Supply. HS Comparator also has Resistor-adjustable Trip Level
• HR Amplifier allows Quiet, <100 µs MOSFET Turn-off for Power Supply Slow Shut Down
• Open Drain, Active Low Fault Output with 120 µs 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 (12 V and 48 V)
• Telecom/Datacom Systems
