Overview
The AP22654WU-7 is a single-channel precision load switch manufactured by Diodes Incorporated, designed for power distribution applications. It operates within a supply voltage range of 3 V to 5.5 V and delivers a maximum output current of 3.14 A. The device features a typical on-resistance (Rds On) of 50 mOhms and includes an adjustable current limit of 3.5 A to protect downstream circuits. Key functional attributes include slew rate control to minimize inrush current, integrated load discharge for rapid output capacitor discharge, and a status flag for fault indication. It supports non-inverting input logic and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates slew rate control to manage turn-on transients and reduce inrush current stress on the power source.
- Includes active load discharge circuitry to rapidly dissipate stored energy in output capacitors when disabled.
- Provides precise current limiting with a status flag output to indicate overcurrent or thermal fault conditions.
Applications
- USB power switching and port protection
- Peripheral power distribution in mobile devices
- Battery-powered equipment load management
Procurement Notes
Verify the specific suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the TSOT-26 package variant matches your PCB footprint requirements. Cross-reference the part number with official Diodes Incorporated documentation to avoid counterfeit components.
Selection Notes
Select this component when precise current limiting and fast discharge are required alongside low on-resistance. The AP22654WU-7 is suitable for applications needing inrush current mitigation without external components. Consider the status flag feature if system monitoring of fault conditions is necessary. Evaluate the 50 mOhm Rds On against thermal dissipation constraints in high-current scenarios.
Part Context
This part belongs to the AP2265x series of precision load switches from Diodes Incorporated. These devices are engineered for compact power management solutions in space-constrained electronics. The series offers various current ratings and package options to suit different power distribution needs while maintaining consistent performance characteristics across the family.
Replacement Considerations
Check Diodes Incorporated application notes for direct pin-compatible alternatives within the AP2265x series. Verify that substitute parts match the 3.14 A output current and 50 mOhm on-resistance specifications. Ensure replacement components support the same 3 V to 5.5 V input voltage range and TSOT-26 packaging.
