AH5795-WU-7

Overview

The AH5795-WU-7 is a single-phase Hall driver manufactured by Diodes Incorporated, designed for motor and motion control applications. It operates within a supply voltage range of 1.8 V to 6 V and delivers an output current capability of 500 mA. The device functions reliably across an extended temperature spectrum from -40°C to +105°C while maintaining a low quiescent operating current of 2.2 mA. It utilizes a TSOT-23-6 surface-mount package and supports SMD/SMT installation methods.

Feature Summary

• Integrates Hall sensing interface with dedicated power driver stage for single-phase motor control
• Provides robust thermal performance suitable for high-temperature operational environments
• Features low power consumption architecture optimized for battery-operated or efficiency-critical systems

Applications

• Fan motor control systems
• Brushed DC motor drivers
• Small appliance motion controllers

Procurement Notes

This component has reached End-of-Life status, with manufacturer discontinuance notifications issued in August 2026. Availability is restricted, and distributors may not stock this item in all regions. Engineers must verify current supply chain status before finalizing designs. Alternative sourcing strategies should be evaluated immediately to mitigate production risks associated with obsolete components.

Selection Notes

Designers should prioritize the AH5795 series for applications requiring integrated Hall signal processing and direct drive capabilities. Verify that the required load current does not exceed the 500 mA limit. Ensure the system voltage remains within the specified 1.8 V to 6 V window. Consider the TSOT-23-6 footprint constraints during PCB layout. Thermal management requirements must align with the -40°C to +105°C operating range specifications.

Part Context

The AH5795-WU-7 belongs to the AH579 family of motor controllers and drivers produced by Diodes Incorporated. This series focuses on providing compact, integrated solutions for single-phase motor applications. The specific WU-7 suffix denotes the TSOT-23-6 packaging variant. These components bridge the gap between simple logic control and complex PWM drivers, offering a streamlined approach for basic motor actuation tasks.
