AH2984-YG-13

Overview

The AH2984-YG-13 is a single-chip solution designed for driving two-coil brushless direct current (BLDC) fans and motors. It integrates a Hall-effect sensor, dynamic commutation logic, and power output stages into one package. The device operates within a supply voltage range of 3.8V to 28V and supports a maximum output current of 400mA. It features an operating temperature range from -40°C to +105°C and is housed in an SOT-89-5 surface-mount package.

Feature Summary

• Integrates Hall-effect sensor with dynamic commutation control
• Combines control stage and power stage in a single chip
• Designed specifically for two-coil BLDC fan applications

Applications

• Two-coil brushless DC fan drivers
• Small BLDC motor control systems
• Thermal management modules in consumer electronics

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm the specific suffix matches project requirements. Check current lifecycle status as availability may vary. Ensure storage conditions comply with manufacturer guidelines for moisture-sensitive devices prior to assembly.

Selection Notes

Select this component when a compact, integrated solution for two-coil BLDC fans is required. It eliminates external discrete components by combining sensing and power driving capabilities. Verify that the 400mA current rating and 28V maximum voltage align with the target motor specifications before finalizing the design.

Part Context

This part belongs to the AH2984 series from Diodes Incorporated, which focuses on simplified BLDC motor drive solutions. The series targets applications requiring reduced bill-of-materials count and board space. The YG-13 suffix typically denotes the specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Consult official Diodes Incorporated documentation for verified cross-reference part numbers. Ensure any substitute maintains compatible voltage ratings, current capacity, and pinout configurations to guarantee functional equivalence in existing designs.
