LB11961集成电路（IC）的电机驱动器控制器规格书PDF中文资料

LB11961属于集成电路（IC）的电机驱动器控制器。由安森美半导体制造生产的LB11961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 LB11961 is a single-phase bipolar drive motor driver that easily implements direct PWM motor drive systems with excellent efficiency. The LB11961 is optimal for fan motor drive in personal computer power supply systems and CPU cooling fan systems.

特性 Features

• Single-phase full-wave drive (16V, 1.0A transistors are built in)

• Built-in variable speed function controlled by a thermistor input

The LB11961 can implement quiet, low-vibration variable speed control

using externally clocked high side transistor

direct PWM drive.

• Built-in regenerative diode (Di); only requires a minimal number of

external components.

• Built-in HB

• Minimum speed setting pin (allows full-speed mode operation at startup)

• Operates in full-speed mode when the thermistor is removed.

• Built-in lock protection and automatic recovery circuits

• FG (speed detection) and RD (lock detection) outputs

• Built-in thermal shutdown circuit
