AP22818AM8-13

Overview

The AP22818AM8-13 is a USB power switch IC manufactured by Diodes Incorporated, housed in an 8-pin MSOP package. It features a single high-side N/P-channel output with a maximum continuous current of 3A and an on-resistance of 50 mΩ. The device operates within a voltage range of 2.7V to 5.5V and supports temperatures from -40°C to 85°C. Integrated protections include fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and UVLO. Additional functional features include load release and a status flag.

Feature Summary

• Integrates fixed current limiting, overtemperature shutdown, reverse current blocking, and short-circuit protection for robust fault management.
• Provides load release functionality and a status flag for system monitoring and control.
• Supports bidirectional current flow prevention through reverse current blocking capabilities.

Applications

• USB port power switching and distribution
• Peripheral device power management
• Battery-powered equipment protection

Procurement Notes

Verify the specific suffix AM8-13 against official Diodes Incorporated documentation to confirm the MSOP-8 package configuration. Ensure compatibility with required operating temperature ranges (-40°C to 85°C) and input voltage specifications (2.7V to 5.5V). Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a single-channel high-side switch with 3A capacity and low on-resistance is required. Consider the MSOP-8 package for space-constrained designs. Evaluate the integrated protection suite, including UVLO and thermal shutdown, against system safety requirements. Confirm that the 2.7V to 5.5V operating range aligns with the target power supply rails.

Part Context

This part belongs to the AP2281x series of USB power switches from Diodes Incorporated. It shares functional similarities with other members like the AP22818AKAWT-7 but differs in packaging, utilizing an MSOP-8 form factor instead of TSOT-25. The series is designed for portable electronics requiring efficient power distribution and comprehensive fault protection.

Replacement Considerations

Direct substitutes may include other AP2281x variants with compatible electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Consult official cross-reference lists for confirmed equivalent parts.

FAQ
