AH284 - Hall-Effect Smart Fan Motor Controller

General Description

AH284 is a monolithic fan motor controller with Hall sensor’s capability.

It contains two complementary open-drain drivers for motor’s coil driving, automatic lock shutdown and restart function relatively.

Key Features

  • s - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Built-in Zener protection for output driver - Operating voltage: 3.8V~20 V - Output current: IO(AVE) = 500mA for SIP-4/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-4L, SOT23-5L, SOT89-5L.

AH284 Hall-Effect Smart Fan Motor Controller „ Features - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Built-in Zener protection for output driver - Operating voltage: 3.8V~20 V - Output current: IO(AVE) = 500mA for SIP-4/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-4L, SOT23-5L, SOT89-5L „ General Description AH284 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain drivers for motor’s coil driving, automatic lock shutdown and restart function relatively. To avoid coil burning, rotor-lock shutdown detection circuit shut down the output driver if the rotor is blocked and then the automatic recovery circuit will try to restart the motor. This function repeats while rotor is blocked.
