This ORing controller allows • Wide Operating Input Voltage Range, VIN: 1 V to MOSFETs to replace diode rectifiers in power 75 V (VBIAS required for VIN < 5 V) distribution networks thus reducing both power loss and voltage drops. • 100-V Transient Capability • Charge Pump Gate Driver for External N-Channel The LM5050-1/-Q1 controller provides charge pump MOSFET gate drive for an external N-Channel MOSFET and a fast response comparator to turn off the FET when • Fast 50-ns Response to Current Reversal current flows in the reverse direction. The LM5050-1/- • 2-A Peak Gate Turnoff Current Q1 can connect power supplies ranging from 5 V to • Minimum VDS Clamp for Faster Turnoff 75 V and can withstand transients up to 100 V. • Package: SOT-6 (Thin SOT-23-6) Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) 2 Applications LM5050-1 Active OR-ing of Redundant (N+1) Power SOT (6) 2.90 mm × 1.60 mm LM5050-1-Q1 Supplies (1) For all available packages, see the orderable addendum at the end of the data sheet. Full Application Typical Redundant Supply Configuration 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
