This ORing controller allows • Wide Operating Input Voltage Range, VIN: 5V to MOSFETs to replace diode rectifiers in power 75V distribution networks thus reducing both power loss and voltage drops. • +100 Volt Transient Capability • Charge Pump Gate Driver for External N- The LM5050-1 controller provides charge pump gate Channel MOSFET drive for an external N-Channel MOSFET and a fast response comparator to turn off the FET when • Fast 50ns Response to Current Reversal current flows in the reverse direction. The LM5050-1 • 2A Peak Gate Turn-Off Current can connect power supplies ranging from +5V to • Minimum VDS Clamp for Faster Turn-Off +75V and can withstand transients up to +100V. • Package: SOT-6 (Thin SOT-23-6) APPLICATIONS • Active OR-ing of Redundant (N+1) Power Supplies Typical Application Circuits Figure 1. Full Application Figure 2.
