AH287-YL-13

Overview

The AH287-YL-13 is a monolithic fan motor controller manufactured by Diodes Incorporated. It integrates Hall sensor capability and features two complementary open-drain drivers designed for direct coil driving. The device operates within a supply voltage range of 3.8V to 28V, supporting CMOS logic inputs. Packaged in an SOT89-5 configuration, it serves as an integrated solution for controlling brushless DC fans with built-in sensing functionality.

Feature Summary

• Integrates Hall sensor detection capability for precise rotor position monitoring
• Contains dual complementary open-drain output drivers for direct coil actuation
• Supports wide operating voltage range suitable for various system power rails

Applications

• Brushless DC (BLDC) fan motor control systems
• Computer cooling fan driver circuits
• HVAC unit fan speed regulation modules

Procurement Notes

Verify the specific suffix 'YL-13' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOT89-5 package. Cross-reference RoHS compliance status with the latest component declaration documents prior to final procurement authorization.

Selection Notes

Select this component when a single-chip solution combining gate drive and Hall sensing is required for BLDC applications. Evaluate the open-drain output structure against load requirements. Confirm that the 3.8V minimum operating voltage aligns with the target system's power supply characteristics and noise margins.

Part Context

This part belongs to Diodes Incorporated's family of motor controllers and drivers. It is specifically categorized under Hall IC AIO drivers. The product line focuses on integrating control logic with power stages to reduce component count in fan management applications.

Replacement Considerations

Check for legacy status updates as some related variants may be marked obsolete. Verify pin-to-pin compatibility if substituting with other SOT89-5 fan controllers from different manufacturers or alternative series within the same brand.
