Part Number: AH287

Function: HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER

Package: SIP-4L and SOT89-5L Type

Manufacturer: Diodes Incorporated.

Pinouts:

AH287 datasheet

 

Description

AH287 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. Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocked to avoid coil overheat.

Then, the automatic recovery circuit will restart the motor. These protected actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally.

Features

1. On Chip Hall Sensor

2. Rotor-Locked Shutdown

3. Automatically Restart

4. Built-in Zener Protection for Output Driver

5. Operating Voltage: 3.8V~28V

6. Output Current: IO(AVE)= 400mA

7. Lead Free Finish/ RoHS Compliant

Description

The reversible motor driver for output 1.0A for 1 motor can set the output modes to four modes, normal, reverse, stop (idling), and braking in accordance with logic input (2 inputs).

Features

1) Built-in surge absorption diode

2) By built-in power save circuit, current consumption when a motor stops (idles) can be suppressed

3) Output voltage can be optionally set by reference voltage setting pin

4) Built-in thermal shutdown circuit (TSD)

Applications:

Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
