AP22817AKBWT-7

Overview

The AP22817AKBWT-7 is a USB power switch IC manufactured by Diodes Incorporated, designed for high-side switching applications. It features an N-channel MOSFET output capable of handling up to 2A continuous current with a typical on-resistance of 75 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and includes comprehensive protection mechanisms such as fixed current limiting, overtemperature shutdown, reverse current blocking, and UVLO. Packaged in a TSOT-25 surface-mount case, it supports non-inverted enable inputs and provides status flag outputs for fault reporting.

Feature Summary

• Integrated high-side N-channel power switch optimized for USB power distribution
• Built-in protection against short circuits, overcurrent, overtemperature, and reverse current
• Status flag output with de-bouncing capability for reliable fault indication
• Controlled rise time and integrated output discharge for safe capacitive loading

Applications

• USB port power switching in laptops and tablets
• Hot-plug protection for peripheral devices
• Power distribution in consumer electronics
• Telecommunication system interface protection

Procurement Notes

Verify the complete part number including the suffix 'WT-7' to ensure correct tape-and-reel packaging quantity of 3000 units. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any recent product change notices or lifecycle updates that may affect long-term availability. Ensure sourcing channels are authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component when a single-channel high-side switch with 2A capacity and 75 milliohm resistance is required. It is suitable for systems operating between 2.7V and 5.5V where USB compatibility and robust fault protection are critical. Consider the TSOT-25 package size for space-constrained designs requiring surface mount technology.

Part Context

This device belongs to the AP2281x series of USB power switches from Diodes Incorporated. It shares functional similarities with other members like the AP22818 but differs in specific electrical parameters and pin configurations. The series is designed to meet stringent USB standards for thermal and electrical safety in portable computing and communication hardware.

Replacement Considerations

AP22818AKBWT-7 is a confirmed substitute within the same family offering similar functionality.
