ATA6826C数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

A fully protected triple half-bridge designed in smart power SOI technology. It can control up to three different loads by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers can drive currents of up to 1.0A. The drivers are internally connected to form three half-bridges, each separately controllable from a standard serial data interface to combine loads from bulbs, resistors, capacitors, and inductors. The IC supports the application of H-bridges to drive DC motors.

简介

ATA6826C属于集成电路（IC）的全半桥驱动器。由制造生产的ATA6826C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。
