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
