描述 Description

The AAT4910 is a 28V half-bridge dual MOSFET driver for high-current DC-DC converter and motor driver applications. It drives both high-side and low-side N-channel MOSFET switches controlled by a logic input. The internal driver circuitry and MOSFET driver power comes from a 5V input allowing the use of low-threshold MOSFETs. The high-side driver output stage is allowed to float at up to 28V, allowing a broad range of power sources.
The AAT4910 is available in a Pb-free, space-saving SC70JW-8 package and is rated over the -40°C to 85°C temperature range.

簡(jiǎn)介

AAT4910屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由制造生產(chǎn)的AAT4910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)。
