LB11660RV-MPB-H集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LB11660RV-MPB-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LB11660RV-MPB-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 LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively.

Features

• Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver.

• Variable speed control by an external signal.

->Separately-excited upper TR direct PWM control method, enabling silent, low-vibration variable speed control.

• Lowest speed setting possible.

• Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5, Rf determines the limiter value.)

• Kickback absorption circuit built in.

• Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change.

• HB built in.

• Lock protection and automatic reset functions incorporated (including a circuit that changes the ON/OFF ratio according to the power supply voltage).

• RD (lock detection) output.

• Thermal protection circuit incorporated (design guaranteed).
