TPS2113A集成电路（IC）的OR控制器理想二极管规格书PDF中文资料

TPS2113A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TPS2113AOR 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 TPS211xA family of power multiplexers enables

seamless transition between two power supplies

(such as a battery and a wall adapter), each

operating at 2.8 V to 5.5 V and delivering up to 2 A,

depending on package. The TPS211xA family

includes extensive protection circuitry, including userprogrammable

current limiting, thermal protection,

inrush current control, seamless supply transition,

cross-conduction blocking, and reverse-conduction

blocking. These features greatly simplify designing

power multiplexer applications.
