CSD95378BQ5MCT集成電路（IC）的全半橋驅(qū)動器規(guī)格書PDF中文資料

CSD95378BQ5MCT屬于集成電路（IC）的全半橋驅(qū)動器。由美國德州儀器公司制造生產(chǎn)的CSD95378BQ5MCT全半橋驅(qū)動器器件屬于電橋驅(qū)動器電源管理集成電路 (PMIC) 系列，包含兩個或多個功率晶體管，以及在外部器件控制下將其用作開關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對串聯(lián)連接（稱為半橋），因而任意指定晶體管對之間的結(jié)點都可以連接至兩個電源軌中的任一個。這類器件常用于將控制器件（如微控制器）提供的低電平信號轉(zhuǎn)換為操作執(zhí)行器（如步進電機或無刷電機）所需的較大功率信號。

3 Description

The CSD95378BQ5MC NexFET? smart power

stage is a highly-optimized design for use in a highpower,

high-density synchronous buck converter.

This product integrates the driver IC and power

MOSFETs to complete the power stage switching

function. This combination produces high-current,

high-efficiency, and high-speed switching capability in

a small 5-mm × 6-mm outline package. It also

integrates the accurate current sensing and

temperature sensing functionality to simplify system

design and improve accuracy. In addition, the PCB

footprint is optimized to help reduce design time and

simplify the completion of the overall system design.
