AP2172SG-13

Overview

The AP2172SG-13 is a dual-channel high-side power switch from Diodes Incorporated, designed for USB and hot-swap applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1 A per channel with a current limit of 1.4 A. The device features a maximum on-resistance of 110 mOhms and is housed in an SOIC-8 package. It includes thermal limiting, short-circuit protection, and a fault flag output with 7 ms deglitch capability.

Feature Summary

• Dual-channel high-side switching with independent control
• Integrated over-current and thermal protection mechanisms
• Fault reporting via open-drain flag with blanking time

Applications

• USB port power distribution
• Hot-swap connector protection
• Consumer electronics power management

Procurement Notes

Verify the specific suffix SG-13 against the manufacturer datasheet to confirm the SOIC-8 package and active-high enable configuration. Ensure compatibility with system voltage levels between 2.7 V and 5.5 V. Confirm RoHS compliance status through official documentation before integration into regulated products.

Selection Notes

Select this component for designs requiring dual isolated power paths with current limiting. The SOIC-8 package suits surface-mount assembly processes. Consider the 110 mOhm on-resistance for thermal management calculations. Verify that the 1.4 A current limit aligns with load requirements to prevent nuisance tripping during startup transients.

Part Context

This part belongs to the AP2172 family of dual USB power switches. It shares functional similarities with the AP2162 but differs in enable logic polarity. The series is optimized for portable devices and computing peripherals requiring robust power distribution with minimal external components.

Replacement Considerations

AP2162ASG-13 offers identical electrical specifications but utilizes active-low enable logic instead of active-high.
