PT3936中文资料24V All-in-One Single Coil Smart DC Fan IC with FG Output数据手册Prolific规格书

描述 Description

The PT3936 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 motor driver IC is especially designed for OA cooling fan solution or industry equipments such as inverters or fan trays. PT3935 also provides RD signal for revolution detection. PT3936 provides FG function for users to monitor revolution. The supply voltage range is from 4.5V to 30V.
