L6203数据手册集成电路（IC）的全半桥驱动器规格书PDF

描述 Description

The I.C. is a full bridge driver for motor control applications realized in Multipower-BCD technology which combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip. By using mixed technology it has been possible to optimize the logic circuitry and the power stage to achieve the best possible performance. The DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switching speeds. All the logic inputs are TTL, CMOS and µC compatible. Each channel (half-bridge) of the device is controlled by a separate logic input, while a common enable controls both channels. The I.C. is mounted in three different packages.

简介

L6203属于集成电路（IC）的全半桥驱动器。由制造生产的L6203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。
