L6208PD013TR属于集成电路（IC）的电机驱动器控制器。由意法半导体集团制造生产的L6208PD013TR电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

描述 Description

The L6208 device is a DMOS fully integrated

stepper motor driver with non-dissipative

overcurrent protection, realized in BCD

technology, which combines isolated DMOS

power transistors with CMOS and bipolar circuits

on the same chip. The device includes all the

circuitry needed to drive a two phase bipolar

stepper motor including: a dual DMOS full bridge,

the constant off time PWM current controller that

performs the chopping regulation and the phase

sequence generator, that generates the stepping

sequence. Available in PowerDIP24 (20 + 2 + 2),

PowerSO36 and SO24 (20 + 2 + 2) packages, the

L6208 device features a non-dissipative

overcurrent protection on the high-side Power

MOSFETs and thermal shutdown.
