PT3956中文资料5V All-in-One Single Coil Smart DC Fan IC with FG Output数据手册Prolific规格书

描述 Description

The PT3956A is designed for magnetic actuating using a bipolar magnetic field. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. The output driver provides a linear drive to eliminate switching noise. This Hall-effect IC is optimal for notebook cooling fan application.The supply voltage range is from 1.8V to 8.5V and the output current is 400mA.
