TEA3718SDP集成电路（IC）的电机驱动器控制器规格书PDF中文资料

TEA3718SDP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TEA3718SDP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 circuits consist of an LS-TTL compatible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. Two TEA3718 ICs and a few external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.

特性 Features

■ Half-step and full-step mode

■ Bipolar drive of stepper motor for maximum motor performance

■ Built-in protection diodes

■ Wide range of current control 5 to 1500 mA

■ Wide voltage range 10 to 50 V

■ Designed for unstabilized motor supply voltage

■ Current levels can be selected insteps or varied continuously

■ Thermal overload protection

■ Alarm output or pre-alarm output

Applications

The TEA3718 is a bipolar monolithic integrated circuit intended to control and drive the current in one winding of a bipolar stepper motor.
