AH2984-PG-B

Overview

The AH2984-PG-B is a single-chip motor controller 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 a compact SIP-4L package. The device operates within a supply voltage range of 2.5V to 15V and supports a maximum drive current of 3.5 mA per channel. It utilizes Power MOSFET technology for efficient switching. The component is qualified under AEC-Q101 standards, ensuring reliability for automotive applications. Key electrical characteristics include low operating current and robust performance across the specified temperature range.

Feature Summary

• Integrates Hall-effect sensing with dynamic commutation control for simplified BLDC motor drive designs
• Combines control logic and power output stages in a single chip to reduce component count
• Supports operation with two-coil BLDC fan and motor configurations

Applications

• Driving two-coil brushless direct current (BLDC) fans
• Controlling small BLDC motors in automotive systems
• Compact cooling solutions requiring integrated sensor and driver functionality

Procurement Notes

Verify the specific suffix PG-B against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the application voltage remains within the 2.5V to 15V operational range. Confirm AEC-Q101 qualification requirements if deploying in automotive environments. Cross-reference the SIP-4L package dimensions with your PCB footprint library. Check for any recent product change notices that may affect lead times or material composition.

Selection Notes

Select this component when a compact solution for two-coil BLDC motors is required. It is suitable for applications where integrating the Hall sensor and driver reduces board space. Consider the 3.5 mA drive capability for low-power fan applications. Verify compatibility with the system's supply voltage range. This part is ideal for replacing discrete driver circuits with an integrated single-chip solution.
