CSD95373BQ5MT集成電路（IC）的全半橋驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

CSD95373BQ5MT屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由美國(guó)德州儀器公司制造生產(chǎn)的CSD95373BQ5MT全半橋驅(qū)動(dòng)器器件屬于電橋驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列，包含兩個(gè)或多個(gè)功率晶體管，以及在外部器件控制下將其用作開(kāi)關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對(duì)串聯(lián)連接（稱(chēng)為半橋），因而任意指定晶體管對(duì)之間的結(jié)點(diǎn)都可以連接至兩個(gè)電源軌中的任一個(gè)。這類(lèi)器件常用于將控制器件（如微控制器）提供的低電平信號(hào)轉(zhuǎn)換為操作執(zhí)行器（如步進(jìn)電機(jī)或無(wú)刷電機(jī)）所需的較大功率信號(hào)。

3 Description

The CSD95373BQ5M NexFET? smart power stage

is a highly optimized design for use in a high-power,

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 has been

optimized to help reduce design time and simplify the

completion of the overall system design.
