• Integrated fault protection including automatic recovery for overcurrent, short circuit, and overtemperature conditions
• Low quiescent current consumption of 50 uA in shutdown mode to minimize power drain
• Built-in soft-start functionality with controlled rise time to manage inrush currents

Applications

• USB port power switching and protection
• Hot-swap applications requiring controlled power sequencing
• Portable electronic devices and battery-powered systems
• General-purpose load distribution in consumer electronics

Procurement Notes

Verify the specific suffix AW5-7 against the manufacturer datasheet to confirm pinout compatibility and enable polarity. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the part number with the latest Diodes Incorporated release notes to validate active status and avoid obsolete components.

Selection Notes

Select this component for applications requiring a single high-side switch with integrated current limiting and thermal protection. The 2 A output capability suits moderate load requirements typical in USB interfaces. Consider the 60 mOhm on-resistance for efficiency calculations. The SOT-25-5 package offers a small form factor suitable for space-constrained designs. Verify that the 2.7 V minimum operating voltage aligns with the system's power rail specifications.

Part Context

This part belongs to the AP228xx series of power switches from Diodes Incorporated, which are engineered for robust load management. The series provides integrated protection features to simplify design and enhance system reliability. The AP22802 variant specifically targets single-channel applications with defined current limits and low standby consumption, fitting into the broader portfolio of PMIC solutions for portable electronics.

Replacement Considerations

The AP22811AW5-7 is a similar single-channel high-side switch within the same family. Verify if the different on-resistance or timing parameters meet the specific application requirements before substitution.
