LM5051MAE/NOPB General Description

The LM5051 Low Side OR-ing FET Controller operates in conjunction with an external MOSFET as an ideal diode rectifier when connected in series with a power source. This OR-ing controller allows MOSFETs to replace diode rectifiers in power distribution networks thus reducing both power loss and voltage drops.

The LM5051 controller provides gate drive for an external N-Channel MOSFET and a fast response comparator to turn off the FET when current flows in the reverse direction. The LM5051 can connect power supplies ranging from -6V to -100V and can withstand transients up to -100V.

The LM5051 also provides a FET test diagnostic mode which allows the system controller to test for shorted MOSFETs.

Key Features

Wide operating input voltage range: -6V to -100V
-100V Transient Capability
Gate drive for external N-Channel MOSFET
MOSFET diagnostic test mode
Fast 50ns response to current reversal
2A peak gate turn-off current
Package: 8-Lead SOIC

Quickly. i recommend.

C**n 11/26/2022

Controllers are stitched, everything is fine. Mk legs are not brazed, they can be considered new. Packaging is not antistatic package, but in some silicone package.
