Overview
The AP22817BKEWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for high-side load switching applications. It operates within a voltage range of 2.7V to 5.5V and supports an output current of 2A with a typical on-resistance of 75 milliohms. The device features non-inverting control logic and includes integrated protection mechanisms such as fixed current limiting, over-temperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). It provides status flagging capabilities and utilizes a TSOT-25 surface-mount package.
Feature Summary
- Integrates comprehensive fault protection including over-temperature, reverse current, and UVLO for robust system reliability
- Provides real-time operational status feedback through dedicated status flag outputs
- Supports high-current load switching with low on-resistance for efficient power distribution
Applications
- USB port power management in consumer electronics
- High-side load switching for peripheral devices
- Power distribution circuits requiring reverse current protection
Procurement Notes
Verify the specific suffix 'EWT' against the manufacturer's official datasheet to confirm tape-and-reel quantity and packaging specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with Diodes Incorporated documentation to validate availability and any recent product change notifications before finalizing procurement plans.
Selection Notes
Select this component when a single-channel high-side switch with integrated status reporting is required. It is suitable for designs needing 2A capacity with low conduction losses. Consider the TSOT-25 package size for space-constrained layouts. Verify that the 2.7V to 5.5V operating range aligns with the system supply voltage and that non-inverting control logic matches the interface requirements.
Part Context
This part belongs to the AP2281x series of USB power switches from Diodes Incorporated. The series is engineered for portable and industrial applications requiring reliable power distribution. Similar models in the family may vary in pin configuration or protection features, necessitating careful comparison of datasheets for specific design integration.
