CSD95377Q4M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CSD95377Q4M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(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(diǎn)都可以連接至兩個(gè)電源軌中的任一個(gè)。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(jìn)電機(jī)或無刷電機(jī)）所需的較大功率信號。

3 Description

The CSD95377Q4M NexFET? 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. The

driver IC has built-in selectable diode emulation

function enables Discontinuous Conduction Mode

(DCM) operation to improve light load efficiency. This

combination produces high-current, high-efficiency,

and high-speed switching capability in a small 3.5

mm × 4.5 mm outline package. In addition, the PCB

footprint has been optimized to help reduce design

time and simplify the completion of the overall system

design.
