TEA3718中文资料步进电机驱动器数据手册ST规格书

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

• Current levels can be selected insteps or varied continuously
• Designed for unstabilized motor supply voltage
• Alarm output or pre-alarm output
• Half-step and full-step mode
• Built-in protection diodes
• Bipolar drive of stepper motor for maximum motor performance
• Wide voltage range 10 to 50 V
• Thermal overload protection
• Wide range of current control 5 to 1500 mA

简介

TEA3718属于集成电路（IC）的电机驱动器控制器。由制造生产的TEA3718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。
