CSD95375Q4M集成電路（IC）的全半橋驅動器規(guī)格書PDF中文資料

CSD95375Q4M屬于集成電路（IC）的全半橋驅動器。由美國德州儀器公司制造生產(chǎn)的CSD95375Q4M全半橋驅動器器件屬于電橋驅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 CSD95375Q4M 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 NexFET technology to

complete the power stage switching function. The driver IC has a built-in selectable diode emulation

function that enables DCM operation to improve light

load efficiency. In addition, the driver IC supports

ULQ mode that enables Connected Standby for Windows? 8. With the PWM input in tri-state,

quiescent current is reduced to 130 μA, with

immediate response. When SKIP# is held at tri-state,

the current is reduced to 8 μA (typically 20 μs is

required to resume switching). This combination

produces a high current, high efficiency, and high

speed switching device in a small 3.5 × 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.
