AP22814AW5-7

Overview

The AP22814AW5-7 is a single-channel high-side load switch manufactured by Diodes Incorporated, designed for power distribution and USB applications. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers an output current of up to 3.8 A with a maximum on-resistance of 65 mΩ. The device features a fixed current limit of 3.8 A and includes integrated protection against overcurrent, short circuits, and overheating. It utilizes a compact SOT-25-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated high-side switching with low on-resistance for efficient power distribution
• Comprehensive protection including automatic recovery from overcurrent, short circuit, and thermal events
• Built-in soft-start functionality to control rise time and mitigate inrush currents
• Open-drain flag output with de-bouncing capability for reliable fault reporting

Applications

• USB power switches and hubs
• Laptop and tablet peripheral power management
• Set-top boxes and consumer electronics
• Telecommunications systems

Procurement Notes

Verify the specific suffix 'W5' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is planned. Confirm RoHS compliance status through official documentation prior to finalizing component selection for regulated markets.

Selection Notes

Select this component when a single-channel high-side switch with robust short-circuit protection and automatic recovery is required. The 65 mΩ on-resistance suits moderate current loads up to 3.8 A. Consider the SOT-25-5 package for space-constrained PCB layouts. Verify that the 2.7 V minimum operating voltage aligns with your system's power rail availability during all operational states.

Part Context

This part belongs to the AP228xx series of load switches from Diodes Incorporated, optimized for USB and general-purpose power distribution. These devices are engineered to provide complete protection solutions for capacitive loads and potential short circuits. The series emphasizes ease of use by requiring minimal external components while offering features like controlled rise times and reverse current blocking.

Replacement Considerations

Cross-reference with AP22811AW5-7 or AP22818AKAWT-7 for similar form-factor alternatives. Verify that substitute parts meet the 3.8 A current limit and 65 mΩ on-resistance specifications. Ensure compatibility with the SOT-25-5 package and check for any differences in enable logic polarity or flag output configurations.
