XC8111AA018R-G

Overview

The XC8111AA018R-G is a single-channel load switch IC manufactured by Torex Semiconductor, featuring an integrated ideal diode function. It operates within a supply voltage range of 1.5 V to 6 V and supports a maximum output current of 1 A with a current limit of 1.7 A. The device exhibits a maximum on-resistance of 880 mOhms and dissipates up to 900 mW of power. Designed for surface-mount installation, it utilizes the USP-6B06 package and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates ideal diode functionality to prevent reverse current flow without external components
• Provides high-side switching capability with P-channel output configuration
• Includes built-in overcurrent protection and thermal shutdown mechanisms

Applications

• Battery-powered portable electronic devices requiring efficient power distribution
• Consumer electronics utilizing multiple voltage rails for component isolation
• Industrial control systems needing protected load switching in harsh environments

Procurement Notes

Verify the specific suffix 'R-G' corresponds to the required tape and reel packaging format when ordering. Confirm that the USP-6B06 package dimensions align with your PCB footprint constraints. Ensure the input voltage does not exceed the 6 V maximum rating during operation. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process. Validate the thermal performance under maximum load conditions to ensure the 900 mW dissipation limit is not exceeded.

Selection Notes

Select this component when a single-channel load switch with ideal diode behavior is required for voltages between 1.5 V and 6 V. Choose this part over standard switches if reverse current blocking is necessary without additional diodes. Consider the 1 A output capacity and 880 mOhms on-resistance for efficiency requirements. Evaluate the USP-6B06 package size against available board space compared to other series options like the XC8112.

Part Context

This device belongs to the XC8111 series of load switches from Torex Semiconductor, designed for compact power management applications. It complements other series such as the XC8110 and XC8112, which offer different channel counts or current ratings. The series focuses on integrating protection features into small form-factor packages suitable for modern mobile and embedded designs.
