AP2181WG-7

Overview

The AP2181WG-7 is a high-side power distribution switch manufactured by Diodes Incorporated. It provides a single output channel with a continuous load current of 1.5 A and a fixed current limit of 2.1 A. The device operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 115 mOhms, a maximum turn-on time of 50 us, and a maximum turn-off time of 10 us. It functions in an industrial temperature range from -40 C to +85 C and utilizes an SOT-25 surface-mount package.

Feature Summary

Integrates a high-side switch topology for direct load control
Includes built-in protection against overcurrent, thermal overload, and reverse current conditions
Features under-voltage lockout (UVLO) to ensure stable operation during power transitions

Applications

USB port power switching and distribution
Peripheral power management in consumer electronics
Battery-powered device load control

Procurement Notes

Verify the specific suffix 'WG-7' matches the required SOT-25 package and reel packaging configuration. Confirm that the manufacturer designation aligns with Diodes Incorporated specifications. Ensure environmental compliance requirements such as RoHS status are validated against the latest datasheet documentation before finalizing procurement orders.

Selection Notes

Select this component when a 1.5 A continuous current rating is sufficient for the application load. The 115 mOhm on-resistance offers a balance between conduction losses and cost. Consider the 2.7 V minimum operating voltage to ensure compatibility with the system's power rail availability during all operational states.

Part Context

This part belongs to the AP2181 series of USB power switches designed for power distribution applications. It serves as a compact solution for managing power delivery to peripheral devices. The series focuses on integrating protection features within a small footprint to support modern portable electronic designs requiring efficient power management.
