Overview
The AP22818AKBWT-7 is a single-channel USB power switch from Diodes Incorporated, designed for high-side load switching applications. It operates within a voltage range of 2.7V to 5.5V and supports a maximum output current of 2A. The device features an on-resistance of 75 milliohms and utilizes a TSOT-25 surface-mount package. Integrated protections include fixed current limiting, overtemperature shutdown, reverse current blocking, short-circuit protection, and under-voltage lockout (UVLO). It provides a status flag output and requires no external supply voltage.
Feature Summary
- Integrated fault protection against overcurrent, thermal overload, reverse current, and short circuits
- Built-in status flag output for system monitoring without external components
- Controlled load release functionality for safe capacitor discharge
- High-side N/P channel switching with non-inverting enable input
Applications
- USB port power switching in laptops and tablets
- Hot-plug protection for peripheral devices
- Power distribution in consumer electronics
- Telecommunication equipment load drivers
Procurement Notes
Verify the specific suffix AKBWT-7 against the manufacturer datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the component meets RoHS3 and REACH compliance requirements for your target market. Cross-reference the ordering code with official Diodes Incorporated documentation to avoid substitution errors during procurement.
Selection Notes
Select this component when a compact, single-channel solution with integrated USB-compliant protections is required. The 75 milliohm resistance offers a balance between efficiency and cost for 2A loads. Consider the TSOT-25 package size for space-constrained designs requiring high-side switching with minimal external circuitry.
Part Context
This part belongs to the AP22818 series of single-channel, current-limited high-side switches. It is functionally similar to the AP22816 and AP22817 variants but optimized for specific current and resistance characteristics. The series is designed to replace legacy discrete solutions by integrating protection logic into a small footprint.
Replacement Considerations
The AP22818AKAWT-7 is a manufacturer-recommended substitute for discontinued or alternative stock versions. Verify pin-to-pin compatibility and electrical parameter alignment before replacing the AKBWT-7 variant in existing designs.
