L6204集成电路（IC）的全半桥驱动器规格书PDF中文资料

L6204属于集成电路（IC）的全半桥驱动器。由意法半导体集团制造生产的L6204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。

DESCRIPTION

The L6204 is a dual full bridge driver for motor

control applications realized in 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 logic inputs are TTL/CMOS compatible. Both

channels are controlled by a separate Enable.

Each bridge has a sense resistor to control the

currenrt level.

The L6204 is mounted in an 20-lead Powerdip and

SO 24+2+2 packages and the four center pins are

used to conduct heat to the PCB. At normal operating temperatures no external heatsink is required.
