TPS2111集成電路（IC）的OR控制器理想二極管規(guī)格書PDF中文資料

TPS2111屬于集成電路（IC）的OR控制器理想二極管。由德州儀器制造生產(chǎn)的TPS2111OR 控制器，理想二極管理想二極管控制器也稱為 OR-ing 控制器，可用于以僅允許單向電流的方式控制外部通道晶體管（通常為 FET），類似于整流二極管，但傳導(dǎo)損耗低得多。在其他應(yīng)用中，它們通常用于在為了冗余和增加電流輸出能力而并行連接的電源中提供逆流保護(hù)。

DESCRIPTION

The TPS211x family of power multiplexers enables seamless transition between two power supplies, such as a

battery and a wall adapter, each operating at 2.8-5.5 V and delivering up to 1 A. The TPS211x family includes

extensive protection circuitry, including user-programmable 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.
