WLC1150-68LQXQT

Overview

The WLC1150-68LQXQT is a highly integrated wireless charging transmitter IC designed for high-power applications. It supports up to 50W output power and complies with Qi 1.3.x specifications, including the Extended Power Profile (EPP). The device features an integrated USB Type-C PD controller supporting Sink mode. It operates within a supply voltage range of 20V and functions across a temperature range of -40°C to +105°C. The component is housed in a 68-pin QFN package.

Feature Summary

• Integrates a USB Type-C PD controller with Sink support for versatile power negotiation capabilities.
• Supports Qi 1.3.x compliance with Extended Power Profile for high-power wireless transmission.
• Utilizes Infineon's proprietary protocol to deliver up to 50W of output power.
• Includes built-in thermal management and foreign object detection tuning.

Applications

• Consumer electronics requiring high-power wireless charging
• Industrial equipment needing robust wireless power solutions
• Devices utilizing USB Type-C PD sink functionality

Procurement Notes

Verify current lifecycle status as the manufacturer has indicated this part is scheduled for obsolescence and will be discontinued. Confirm availability through authorized distributors before finalizing design-in decisions. Ensure compatibility with existing firmware and hardware designs given the end-of-life notification.

Selection Notes

Select this component for designs requiring integrated Qi EPP and USB-PD Sink capabilities in a single transmitter solution. Consider the 68-QFN package constraints and thermal requirements for 50W operation. Evaluate alternative parts if long-term supply stability is critical due to the discontinuation notice.

Part Context

This IC belongs to Infineon's WLC series of wireless charging controllers. It is specifically engineered for transmitters that require both standard Qi compatibility and advanced power delivery features. The integration reduces bill-of-materials count by combining power stage control with communication protocols.

Replacement Considerations

Check for WLC1115-68LQXQT for lower power (15W) requirements. Verify specific pin-to-pin or functional equivalents from other manufacturers if supply continuity is required due to the end-of-life status.
