TPS2419PWR

TPS2419PWR概述

N + 1或运算电源轨控制器启用 N+1 and ORing Power Rail Controller with Enable

DESCRIPON

The TPS2419 controller, in conjunction with an external N-channel MOSFET, provides the reverse current protection of an ORing diode with the efficiency of a MOSFET. The TPS2419 can be used to combine multiple power supplies to a common bus in an N+1 configuration, or to combine redundant input power buses.

Applications for the TPS2419 include a wide range of systems including servers and telecom. These applications often have either N+1 redundant power supplies, redundant power buses, or both. Redundant power sources must have the equivalent of a diode OR to prevent reverse current during faults and hotplug.

FEATURES

• Control External FET for N+1 and ORing
