L9935集成电路（IC）的电机驱动器控制器规格书PDF中文资料

L9935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L9935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 L9935 is a two-phase stepper motor driver circuit suited to drive bipolar stepper motors.

The device can be controlled by a serial interface (SPI). All protections required to design a well protected system (short-circuit, over temperature, cross conduction etc.) are integrated.

特性 Features

■ 2 x 1.1 A full bridge outputs

■ Integrated chopping current regulation

■ Minimized power dissipation during flyback

■ Output stages with controlled output voltage slopes to reduce electromagnetic radiation

■ Short-circuit protection of all outputs

■ Error-flag for over load, open load and over temperature pre alarm

■ Delayed channel switch on to reduce peak currents

■ Max. operating supply voltage 24 V

■ Standby consumption typically 40 µA

■ Serial interface (SPI)
