AP22816AKCWT-7

Overview

The AP22816AKCWT-7 is a single-channel high-side power distribution load switch manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7V to 5.5V and supports a continuous output current of 1A. The device features a typical on-resistance of 75mΩ and includes built-in soft-start with a typical rise time of 0.6ms. Integrated protections include overcurrent, short-circuit, and overtemperature protection with auto-recovery capabilities, alongside output reverse current and voltage protection. A fault report flag (FLG) provides status indication with a 6ms typical blanking time. ESD protection ratings are 2kV HBM and 500V CDM. It is housed in a TSOT-25 package.

Feature Summary

• Integrated high-side switching with low on-resistance for efficient power distribution
• Comprehensive fault protection including overcurrent, short-circuit, and overtemperature with auto-recovery
• Status reporting via fault flag pin with defined blanking time
• Robust electrostatic discharge protection for sensitive electronic environments

Applications

• Ultrabook PC integrated load switches
• Power up/down sequencing in portable computing devices
• Solid state drive (SSD) power management
• Consumer electronics and tablet PCs
• Set-top boxes and telecom systems

Procurement Notes

Verify the specific suffix 'AKCWT-7' against official Diodes Incorporated documentation to confirm active-high logic enable and TSOT-25 packaging. Ensure compatibility with system voltage requirements between 2.7V and 5.5V. Confirm thermal performance meets application needs given the 75mΩ on-resistance. Check for RoHS3 compliance and moisture sensitivity level 1 requirements during storage and handling.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with 1A current capability. It is suitable where space is constrained due to the TSOT-25 package. Consider the auto-recovery feature if transient faults are expected. Verify that the 2.7V minimum operating voltage aligns with the system's power rail. The non-inverting logic interface simplifies control circuitry design.
