TPS2419DR集成电路（IC）的OR控制器理想二极管规格书PDF中文资料

TPS2419DR属于集成电路（IC）的OR控制器理想二极管。由德州仪器制造生产的TPS2419DROR 控制器，理想二极管理想二极管控制器也称为 OR-ing 控制器，可用于以仅允许单向电流的方式控制外部通道晶体管（通常为 FET），类似于整流二极管，但传导损耗低得多。在其他应用中，它们通常用于在为了冗余和增加电流输出能力而并行连接的电源中提供逆流保护。

DESCRIPTION

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.

Accurate voltage sensing and a programmable

turn-off threshold allows operation to be tailored for a

wide range of implementations and bus

characteristics. The TPS2419 brings out an enable

pin which allows the system to force the MOSFET off

under light-load, high noise conditions.
