Overview
The AP22817BKBWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for portable electronic applications. It operates within a supply voltage range of 2.7V to 5.5V and supports a continuous output current of 2A. The device features an on-resistance of 75 milliohms and includes integrated protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). Packaged in a TSOT-25 surface-mount format with a factory quantity of 3000 units per reel, it functions across a temperature range of -40°C to 85°C.
Feature Summary
- Integrates comprehensive fault protection including over-temperature, current limit, and reverse current blocking
- Provides status indication through an integrated flag output
- Supports high-speed switching with controlled slew rates to minimize inrush current
Applications
- USB peripheral power distribution
- Portable consumer electronics power management
- Battery-powered device load switching
Procurement Notes
Verify the specific suffix 'BKBWT-7' against the manufacturer's official datasheet to confirm pinout configuration and electrical tolerances. Ensure the ordering code matches the required tape-and-reel packaging quantity of 3000 units. Cross-reference RoHS compliance documentation and product change notifications prior to finalizing procurement orders.
Selection Notes
Select this component when a compact USB power switch with integrated status monitoring is required. The 75 milliohm on-resistance offers efficient power delivery for loads up to 2A. Consider the TSOT-25 package for space-constrained designs requiring surface-mount assembly. Validate that the operating voltage range aligns with the system's power rail specifications.
Part Context
This part belongs to the AP2281x series of USB power switches from Diodes Incorporated. It shares functional similarities with models like the AP22818 and AP2822, offering comparable protection features in a small footprint. The series targets applications requiring reliable power path management with minimal external component count.
Replacement Considerations
The AP2822GKTR-G1 is listed as a discontinued alternative with a recommended replacement of AP22818AKWT-7. Verify pin compatibility and parameter alignment before substituting.
