AH285-YG-13

Overview

The AH285-YG-13 is a Hall-effect smart fan motor controller manufactured by Diodes Incorporated. It integrates control logic and power stages for brushless DC fan motors within an SOT-89-5 package. The device operates on a supply voltage range of 3.8V to 20V with a maximum output current of 500mA. It supports low-side switching configurations and utilizes open-loop or closed-loop speed control methods depending on the specific application requirements.

Feature Summary

Integrates Hall-effect sensing interface for rotor position detection
Combines control logic with integrated power MOSFET drivers
Supports variable speed control via external resistor or PWM input

Applications

Brushless DC fan motor control in computer cooling systems
Smart fan applications requiring integrated drive and control
Thermal management solutions in consumer electronics

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors. Confirm RoHS compliance status using official documentation. Ensure the SOT-89-5 package matches design specifications. Check for end-of-life notifications as this series may have discontinuation notices. Validate electrical parameters against the latest datasheet revision before integration.

Selection Notes

Select this component for applications requiring a compact, integrated solution for BLDC fan control. The SOT-89-5 package offers space efficiency compared to discrete driver designs. Consider the 500mA current limit when sizing for higher-power fans. Verify compatibility with the system's Hall sensor type and operating voltage range of 3.8V to 20V.

Part Context

The AH285 belongs to the AH28x family of smart fan controllers from Diodes Incorporated. This family provides integrated solutions for managing brushless DC motors in thermal management applications. The AH285 specifically targets cost-sensitive and space-constrained designs where integrating control and power stages reduces bill of materials complexity.
