Overview
The AP22817AKEWT-7 is a single-channel USB power switch IC manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7V to 5.5V and supports an 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, over-temperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout. The component functions with a non-inverting control interface and provides status flag and load release capabilities.
Feature Summary
- Integrates high-side N/P channel switching for USB power distribution applications
- Provides robust fault protection including over-temperature, short-circuit, and reverse current blocking
- Delivers low on-resistance for efficient power delivery in compact surface-mount packaging
Applications
- USB hub power management
- Portable electronic device power switching
- Peripheral connection power control
Procurement Notes
Verify the specific suffix 'AKEWT-7' against official Diodes Incorporated documentation to confirm tape and reel quantity and material compliance. Ensure the ordering part number matches the required package variant and environmental specifications. Cross-reference datasheet revision dates to validate feature availability and electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with 2A capacity and integrated USB-specific protections is required. Consider the TSOT-25 footprint for space-constrained designs. Evaluate thermal performance requirements given the 75 milliohm resistance and operating temperature range. Confirm compatibility with system logic levels for the non-inverting control input.
Part Context
This part belongs to the AP22816/17/18 family of single-channel, current-limited high-side switches from Diodes Incorporated. These devices are designed specifically for USB power switching applications requiring compact solutions. The series offers variations in current ratings and pin configurations while maintaining consistent protection features and control interfaces across the product line.
Replacement Considerations
AP22816AKEWT-7 serves as a verified substitute within the same family, offering similar functionality with different current handling capabilities. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official manufacturer cross-reference data to ensure functional equivalence and mechanical fit for the target application.
