AP22816BKBWT-7

Overview

The AP22816BKBWT-7 is a single-channel power distribution load switch manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7V to 5.5V and features a typical on-resistance of 75mΩ. The device supports output currents up to 2.0A and includes built-in soft-start with a typical rise time of 0.6ms. Key protection mechanisms include auto-recovery overcurrent, short-circuit, and overtemperature protection, alongside output reverse current and voltage safeguards. It utilizes a TSOT-25 package and offers logic-level enable control.

Feature Summary

• Integrated fault report flag with blanking time for accurate status monitoring
• Auto-recovery protection against overcurrent, short-circuit, and thermal events
• Built-in soft-start functionality to manage inrush current during power-up
• Reverse current and voltage protection to prevent backflow

Applications

• Integrated load switches in Ultrabook PCs
• Power up/down sequencing in portable computing devices
• Solid state drives (SSD) power management
• Consumer electronics and tablet PC power distribution

Procurement Notes

Verify the specific suffix 'B' indicates active-low enable logic as per Diodes Incorporated documentation. Confirm the 'K' package code corresponds to the TSOT-25 form factor and 'WT' denotes tape-and-reel packaging. Ensure RoHS compliance and halogen-free status are required for the target assembly process. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a single-channel high-side switch with 75mΩ resistance and 2.0A capability is required. The active-low enable option suits systems where low signals trigger power delivery. Consider the 0.6ms soft-start for sensitive loads. Verify that the 2.7V to 5.5V operating range aligns with the system's supply rails and that the TSOT-25 footprint fits the PCB layout constraints.

Part Context

This part belongs to the AP22816 series of single-channel load switches from Diodes Incorporated. The series provides various current ratings and enable polarities. The AP22816B variant specifically offers the active-low enable configuration. It is designed for general-purpose power switching applications requiring robust protection and compact surface-mount packaging.

Replacement Considerations

Compatible substitutes within the same family include AP22816AKBWT-7, which shares identical electrical characteristics but features an active-high enable pin instead of active-low. Both parts utilize the TSOT-25 package and maintain the 75mΩ on-resistance and 2.0A current rating specifications.
