AM2355N数据手册AMtek中文资料规格书

描述 Description

The AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (Back
Electro-Motive Force) of the motor in rotation and provides corresponding commutation current to
the motor. Rotation speed can be controlled by PWM input signal. The drivers include Lock
Detection, Thermal Shutdown, and Over-current Protection. Forward and Reverse control.

特性 Features

1) Operation voltage 1.8 to 6.0V
2) Lock detection/Automatic restart function
3) Built-in FG (frequency generation)
4) Thermal shutdown protection
5) Over current protection
6) PWM speed control
7) Soft switching technique to reduce acoustic noise
8) Forward and Reverse control

应用 Application

3-phase sensor-less DC Fan Motor
