LV8731V-TLM-H集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LV8731V-TLM-H属于集成电路（IC）的电机驱动器控制器。由安森美半导体公司制造生产的LV8731V-TLM-H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。

Overview

The LV8731V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports 4W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepping motors used in office equipment and amusement applications.

Features

• Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated.

• BiCDMOS process IC

• Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A)

• Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase

• Excitation step proceeds only by step signal input

• Motor current selectable in four steps

• Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated

• Unusual condition warning output pins

• No control power supply required
