LM5050-1

High Side OR-ing FET Controller

General Description

Features

The LM5050-1 High Side OR-ing FET Controller operates in

conjunction with an external MOSFET as an ideal diode rec-

tifier when connected in series with a power source. This

ORing controller allows MOSFETs to replace diode rectifiers

in power distribution networks thus reducing both power loss

and voltage drops.

Wide Operating Input Voltage range, V_IN: 5V to 75V

■

+100 Volt transient capability

Charge pump gate driver for external N-Channel MOSFET

Fast 50ns response to current reversal

2A peak gate turn-off current

Minimum V_DSclamp for faster turn-off

Package: TSOT-6 (Thin SOT23-6)

The LM5050-1 controller provides charge pump gate drive for

an external N-Channel MOSFET and a fast response com-

parator to turn off the FET when current flows in the reverse

direction. The LM5050-1 can connect power supplies ranging

from +5V to +75V and can withstand transients up to +100V.

Applications

Active OR-ing of Redundant (N+1) Power Supplies
