AH288-YG-13

Overview

The AH288-YG-13 is a monolithic Hall-effect smart fan motor controller manufactured by Diodes Incorporated. It integrates two complementary open-drain transistors as motor coil drivers, designed for brushless DC (BLDC) fan applications. The device operates within a supply voltage range of 3.8V to 28V and supports an output current of 400mA. It features rotor-locked shutdown with automatic restart capabilities to prevent coil damage. The component utilizes a SOT-89-5 surface-mount package and includes built-in Zener protection for the output driver.

Feature Summary

Integrates Hall sensor capability with dual complementary open-drain transistor drivers for direct motor control
Includes rotor-locked shutdown detection circuit that automatically attempts recovery if the motor is blocked
Provides frequency generator (FG) output signal for relative speed detection
Features built-in Zener protection on the output driver to enhance reliability

Applications

Brushless DC (BLDC) fan motor control
Smart fan motor driver circuits
Speed detection systems utilizing FG output

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Diodes Incorporated. Verification of availability should focus on authorized distributors or surplus channels, as standard production supply is discontinued. Confirm RoHS compliance status through official documentation before integration into new designs.

Selection Notes

Select this part for single-phase BLDC fan applications requiring integrated Hall sensing and driver functionality. Ensure the design accommodates the SOT-89-5 package constraints and the 3.8V to 28V operating voltage range. Consider the automatic restart feature when designing thermal management strategies for potential rotor-lock scenarios.

Part Context

The AH288 belongs to the AH288 series of high-voltage Hall-effect smart fan motor controllers. This family combines magnetic sensing with power driving stages in a single monolithic IC, simplifying the bill of materials for fan control applications compared to discrete solutions.
