AH284-PL-B

Overview

The AH284-PL-B is a Hall-effect smart fan motor controller manufactured by Diodes Incorporated. It serves as a single-chip solution for driving two-coil brushless direct current (BLDC) fans and motors. The device integrates a Hall-effect sensor, dynamic commutation logic, and output drivers. It operates within a supply voltage range of 3.8V to 20V. The component is housed in a SIP-4 package.

Feature Summary

Integrates Hall-effect sensing with dynamic commutation control
Designed specifically for driving two-coil BLDC fans and motors
Provides a complete single-chip motor drive solution

Applications

Brushless DC fan motor control
Two-coil BLDC motor driving
Smart fan applications requiring integrated sensing

Procurement Notes

Verify the specific suffix PL-B against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the operating voltage requirements align with the 3.8V to 20V range specified for this variant. Cross-reference the SIP-4 package dimensions with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact, integrated solution for two-coil BLDC motors is required. It eliminates the need for external Hall sensors and complex gate driver circuits. Consider the SIP-4 package size and the 3.8V to 20V input range when evaluating system power architecture and space limitations.
