Overview
The AH284-PG-B is a Hall-effect smart fan motor controller manufactured by Diodes Incorporated. Designed for driving two-coil brushless direct current (BLDC) fans and motors, this single-chip solution integrates necessary control logic with power drivers. It operates within a supply voltage range of 3.8V to 20V. The device utilizes a SIP-4 package configuration, providing a compact form factor suitable for space-constrained applications. It functions as a pre-driver for DC fans, simplifying the design process for motor control systems.
Feature Summary
- Integrates Hall-effect sensing with motor drive capabilities in a single chip
- Optimized for controlling two-coil BLDC fans and motors
- Operates across a wide supply voltage range from 3.8V to 20V
Applications
- Brushless DC fan motor control
- Two-coil BLDC motor driving
- Smart fan pre-driver circuits
Procurement Notes
Verify the specific package type SIP-4 against your PCB footprint requirements. Confirm that the operating voltage range of 3.8V to 20V aligns with your system's power supply rails. Ensure thermal management considerations are addressed for the intended application environment. Check for any RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a integrated solution for two-coil BLDC fans is required. It eliminates the need for separate Hall sensors and discrete driver transistors. Consider the SIP-4 package constraints during layout. Verify that the input voltage does not exceed the maximum rating of 20V under all operating conditions.
Part Context
This part belongs to the family of Hall-effect smart fan controllers produced by Diodes Incorporated. These devices are engineered to simplify the implementation of brushless DC motor drives. The AH284 specifically targets applications requiring reliable control of small fans with minimal external components.
