LB1975数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

LB1975 is a 3-phase brushless motor driver IC suited for use in direct PWM driving DC fan motors for air conditioners, water heaters and other similar equipment. Because a shunt regulator circuit is built in, single power supply operation sharing the same power supply for the motor is supported.

特性 Features

Withstand voltage 46 V, output current 2.5 A
Direct PWM drive output
3 integrated output top-side diodes
Integrated current limiter
Integrated FG output circuit

应用 Application

Fan motor control
Air conditionersWater heaters

简介

LB1975属于集成电路（IC）的电机驱动器控制器。由制造生产的LB1975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。
