Overview
The AP22816AKBWT-7 is a single-channel USB power switch IC manufactured by Diodes Incorporated. It operates within a load voltage range of 2.7V to 5.5V and supports an output current of 1A. The device features a typical on-resistance of 75 milliohms and utilizes a TSOT-25 surface-mount package. It includes integrated fault protection mechanisms such as fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). Additional functional features include load release capability and a status flag output. The component is designed for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates comprehensive fault protection including fixed current limiting, overtemperature shutdown, reverse current blocking, and short-circuit protection.
- Provides a status flag output and load release functionality for system monitoring and control.
- Supports high-side switching with N/P channel configuration in a compact TSOT-25 package.
Applications
- USB port power distribution and protection
- Battery-powered device power management
- Portable electronics load switching
Procurement Notes
Verify the specific suffix 'KBWT' against the manufacturer's official datasheet to confirm pinout, tolerance, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS3 compliance status through official documentation before integration into production designs.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with integrated USB-specific protections. The 1A current rating and low on-resistance make it suitable for powering peripheral loads. Consider the TSOT-25 package size for space-constrained designs. Verify that the 2.7V minimum operating voltage aligns with the system's supply rails.
Part Context
This part belongs to the AP2281x series of single-channel current-limited high-side switches from Diodes Incorporated. The series shares common architectural features but varies in current ratings and package options. The AP22816 variant specifically targets 1A applications, distinguishing it from higher-current counterparts like the AP22818.
Replacement Considerations
AP22816AKCWT-7 is listed as a substitute option by distributors.
FAQ
Does the AP22816AKBWT-7 support reverse current flow?
No, the device includes reverse current blocking protection to prevent backflow from the load to the source.
What fault conditions trigger the status flag?
The status flag indicates active fault conditions such as overcurrent, overtemperature, or short circuits, depending on the specific implementation defined in the datasheet.
