AP2822CKETR-G1

Power Distribution Switches, Load Drivers Overview

The AP2822CKETR-G1 is a high-side power distribution switch manufactured by Diodes Incorporated, designed for USB power switching applications. It integrates an N-channel MOSFET with a charge pump and protection circuits in a SOT-23-5 package. The device operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 1A. Key electrical characteristics include a typical on-resistance of 85 milliohms and a non-inverting input interface. It functions without a separate supply voltage.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates fixed over-current limiting, thermal shutdown, reverse current protection, and under-voltage lockout.
• Provides a status flag feature for monitoring operational state.
• Utilizes a single non-inverting control input for simple interface compatibility.

Power Distribution Switches, Load Drivers Applications

• USB port power distribution
• High-side load switching
• Power management in portable electronics

Power Distribution Switches, Load Drivers Procurement Notes

This component has reached end-of-life status and is no longer in production. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Designers must confirm the specific manufacturing date code and storage conditions if sourcing from secondary markets. Replacement strategies should prioritize the manufacturer-recommended alternatives to ensure long-term supply chain stability.

Power Distribution Switches, Load Drivers Selection Notes

Select this part for low-cost, single-channel high-side switching where 1A capacity suffices. Verify that the 85 milliohm on-resistance meets thermal requirements for the specific load. Ensure the 2.7V minimum operating voltage aligns with the system's power rail. Consider the SOT-23-5 footprint constraints during PCB layout. Check RoHS3 compliance documentation for environmental regulations.

Power Distribution Switches, Load Drivers Part Context

Part of the AP2822 series, which offers various current ratings and packages. This specific suffix denotes the 1A variant in a SOT-23-5 reel packaging. The series shares common protection features but differs in current handling capabilities. Other variants include higher current options like the 2A models.

Power Distribution Switches, Load Drivers Replacement Considerations

Diodes Incorporated recommends the AP22816AKEWT-7 as a direct replacement. Verify pinout compatibility and ensure the substitute meets the same 1A current and 85 milliohm resistance specifications.
