AAT4910数据手册集成电路（IC）的全半桥驱动器规格书PDF

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.

简介

AAT4910属于集成电路（IC）的全半桥驱动器。由制造生产的AAT4910全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。
