Overview
The AP22818BKCWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for high-side load switching applications. It features an N-channel output with a maximum continuous current of 2A and a typical on-resistance of 75 milliohms. The device operates within a voltage range of 2.7V to 5.5V and includes integrated protection against overcurrent, thermal overload, reverse current, and short circuits. It utilizes a TSOT-25 surface-mount package.
Feature Summary
- Integrated fault protection including fixed current limit, thermal shutdown, and reverse current blocking
- Built-in status flag output with de-bouncing capability to prevent false overcurrent reporting
- Controlled output discharge function ensuring complete capacitor discharge upon disable
Applications
- USB port power distribution in laptops and tablets
- Hot-plug applications in consumer electronics
- Set-top boxes and telecommunications systems
- General-purpose load switching in portable devices
Procurement Notes
Verify the specific suffix 'BKCWT-7' against the manufacturer's official datasheet to confirm pinout configuration and enable polarity. Ensure the component matches the required TSOT-25 package dimensions and lead finish specifications for your PCB assembly process. Cross-reference the RoHS compliance status with the latest product change notifications from Diodes Incorporated prior to ordering.
Selection Notes
Select this component when a compact, single-channel USB power switch with integrated fault protection is required. The 75 milliohm on-resistance supports up to 2A loads efficiently. Consider the non-inverting enable input and the specific status flag characteristics if system monitoring is needed. Verify that the 2.7V to 5.5V operating range aligns with your system's power supply rails.
Part Context
This part belongs to the AP22818 series of USB power switches from Diodes Incorporated. It is functionally similar to variants like the AP22818AKWT-7 but may differ in enable logic or package specifics. The series is optimized for USB standards compliance, offering robust protection features suitable for modern portable electronic devices requiring reliable power management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Diodes Incorporated for direct replacements or cross-references based on specific electrical requirements and package constraints.
