AH291-YL-13

Overview

The AH291-YL-13 is a monolithic fan motor controller featuring Hall sensor capability. It integrates two complementary open-collector drivers for direct motor coil driving. The device operates within a supply voltage range of 1.8V to 5.75V, supporting low-voltage applications. Designed as an all-in-one driver solution, it simplifies circuit design by combining control logic and power output stages in a single package.

Feature Summary

• Integrates Hall sensor detection capability for precise commutation control
• Contains dual complementary open-collector drivers for direct coil actuation
• Monolithic architecture reduces external component count

Applications

• Brushless DC fan motor control
• Low voltage cooling system drives
• Hall-effect based motor positioning

Procurement Notes

Verify the specific suffix 'YL' against the manufacturer's current product lifecycle status, as the base AH291 series may have inactive or obsolete variants. Confirm package availability and lead times directly with authorized distributors, as inventory levels fluctuate. Ensure the operating voltage range aligns with your system's power supply specifications before ordering.

Selection Notes

Select this component when a compact, integrated solution for low-voltage brushless fans is required. It is suitable for designs needing built-in Hall sensing without external discrete sensors. Consider the open-collector output structure for compatibility with load requirements. Evaluate thermal performance if driving high-current coils, as the internal drivers handle the power stage.

Part Context

This part belongs to the AH29x family of low-voltage Hall-effect smart fan motor controllers from Diodes Incorporated. These devices are designed to replace multiple discrete components, offering a simplified approach to managing small DC motors in consumer electronics and computer cooling systems where space and cost efficiency are critical.
