Overview
The AP22818AKAWT-7 is a single-channel USB power switch manufactured by Diodes Incorporated. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 2A. The device features a typical on-resistance of 75 milliohms and utilizes a TSOT-25 surface-mount package. It includes integrated protection against fixed overcurrent, overtemperature, reverse current, short circuits, and under-voltage lockout (UVLO).
Feature Summary
- Integrates comprehensive fault protection including fixed current limiting, thermal shutdown, reverse current blocking, and UVLO.
- Provides status flag indication with debouncing capability to prevent false overcurrent reporting.
- Features controlled load release for complete discharge of output capacitance upon disable or fault conditions.
Applications
- USB port power switching in laptops and tablets
- Hot-plug applications in consumer electronics
- Set-top boxes and telecommunications systems
Procurement Notes
Verify the specific suffix 'AKAWT-7' matches the required enable polarity and packaging configuration. Confirm that the TSOT-25 footprint aligns with the target PCB design. Ensure compliance with RoHS3 standards if required by the end product specifications.
Selection Notes
Select this component for high-side switching applications requiring robust protection against short circuits and reverse currents. The 2A current rating suits most standard USB peripheral loads. Consider the non-inverting enable input logic when designing control circuitry.
Part Context
This part belongs to the AP22818 series of single-channel, current-limited high-side switches designed specifically for USB and general hot-plug applications. It offers a compact solution for managing power distribution in portable devices while maintaining system integrity during fault events.
Replacement Considerations
The AP2822GKATR-G1 is listed as a manufacturer-recommended replacement for discontinued variants, though it specifies an 85 milliohm on-resistance compared to the 75 milliohm typical value of the AP22818 series. Verify pin compatibility before substitution.
