Overview
The AP22816BKCWT-7 is a USB power switch IC manufactured by Diodes Incorporated, housed in a TSOT-25 package. It operates within an input voltage range of 2.7V to 5.5V and supports up to 1A output current. The device features a typical on-resistance (RdsOn) of 75mΩ. Key electrical characteristics include built-in soft-start with a typical rise time of 0.6ms and a fault report flag with blanking time. It provides comprehensive protection against overcurrent, overtemperature, reverse current, short circuits, and under-voltage lockout.
Feature Summary
- Integrated soft-start mechanism with typical 0.6ms rise time to manage inrush current
- Built-in fault reporting flag with blanking time for accurate status monitoring
- Comprehensive protection suite including overcurrent, overtemperature, reverse current, and short circuit safeguards
Applications
- USB port power management in computing devices
- Power switching in consumer electronics peripherals
- Battery-powered device load control
Procurement Notes
Verify the specific suffix 'BKCWT-7' against the official Diodes Incorporated datasheet to confirm pinout and functional compatibility. Ensure the ordering information matches the required tape-and-reel quantity of 3000 units if applicable. Cross-reference the RoHS compliance status and environmental declarations with the latest product change notifications provided by the manufacturer before finalizing procurement.
Selection Notes
Select this component when a compact TSOT-25 footprint is required for USB power switching applications. It is suitable for designs needing 1A continuous current capability with low on-resistance. Consider the integrated fault reporting feature if system-level diagnostics are necessary. Verify that the operating temperature range of -40°C to 85°C meets the environmental requirements of the target application.
Part Context
This part belongs to the AP2281x series of USB power switches from Diodes Incorporated. These devices are designed to provide efficient power distribution and protection for USB interfaces. The series offers various configurations to suit different current ratings and package constraints, supporting the growing demand for reliable power management in portable and stationary electronic systems.
Replacement Considerations
Check for direct substitutes such as the AP22816AKAWT-7 or AP22818AKWT-7, ensuring pin compatibility and electrical parameter alignment. Verify that alternative parts meet the same 1A current rating and 75mΩ on-resistance specifications. Confirm package equivalence and thermal performance before substitution.
