Overview
The AP22818AKCWT-7 is a single-channel USB power switch IC manufactured by Diodes Incorporated, designed for high-side load switching applications. It operates within a 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 comprehensive protection mechanisms such as fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). The component provides status flag functionality and does not require an external supply voltage.
Feature Summary
- Integrates fixed current limiting and overtemperature protection for robust fault management
- Provides reverse current blocking capability to prevent backflow in power systems
- Includes status flag output for real-time monitoring of switch conditions
Applications
- USB port power switching and protection
- High-side load driver circuits
- Portable electronic device power distribution
Procurement Notes
Verify the specific suffix 'AKCWT-7' against official Diodes Incorporated documentation to confirm tape-and-reel quantity and marking details. Ensure compatibility with TSOT-25 footprint requirements during PCB layout. Cross-reference the datasheet for moisture sensitivity level and reflow soldering profiles to maintain component integrity during assembly processes.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with integrated USB-specific protections. Consider the 2A current rating and 75 milliohm on-resistance for efficiency requirements. Evaluate the need for status flag reporting and reverse current blocking when designing power paths for portable devices or USB peripherals.
Part Context
This part belongs to the AP22818 series of single-channel, current-limited high-side switches from Diodes Incorporated. It is functionally related to other variants in the AP22816 and AP22817 families, which offer similar protection features but may differ in current ratings or package options. The series is designed specifically for USB power switching applications requiring compact solutions.
Replacement Considerations
The AP2822GKATR-G1 is listed as a manufacturer-recommended replacement for discontinued AP2822 series parts, though it differs in on-resistance characteristics. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
