AP2181DSG-13

Overview

The AP2181DSG-13 is a single-channel high-side power switch from Diodes Incorporated, optimized for USB and hot-swap applications. It operates within a supply voltage range of 2.7V to 5.5V and supports an output current of 1.5A with a maximum on-resistance of 90 mOhms. The device features a fixed current limit of 2.1A and includes thermal limiting and short-circuit protection. It utilizes a UDFN-6 surface-mount package and functions across an ambient temperature range of -40°C to +85°C.

Feature Summary

Integrated over-current and thermal protection with controlled rise time
Active-low enable input with very low shutdown current
Open-drain flag output with 7ms deglitch capability for fault reporting
Reverse current blocking and under-voltage lockout functionality

Applications

USB port power switching
Hot-swap circuit applications
Peripheral power distribution

Procurement Notes

Verify the specific suffix DSG-13 against the manufacturer datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the active-low enable configuration matches the system design requirements. Confirm RoHS compliance and lead-free finish status through official documentation before procurement.

Selection Notes

Select this component for designs requiring a single-channel high-side switch with integrated fault protection. The 1.5A continuous current rating suits standard USB loads. Verify that the 90 mOhm on-resistance meets efficiency targets. The UDFN-6 package requires appropriate PCB footprint considerations for thermal dissipation and soldering.

Part Context

This part belongs to the AP2181 family of single-channel current-limited power switches. It is designed as a drop-in replacement for discrete MOSFET solutions in USB power paths. The series offers various packages including SOP-8L and MSOP-8L-EP, with the DSG variant specifically denoting the UDFN-6 form factor.
