WLC1115-68LQXQ

Overview

The WLC1115-68LQXQ is a Qi2-compliant wireless charging transmitter IC from Infineon Technologies, designed for high-performance power transfer up to 15 W. It integrates USB Power Delivery (PD) sink capabilities and supports both Qi v1.3.2 and Qi2.x standards. The device operates within an input voltage range of 4.5 V to 24 V and features a supply current of 87 mA. It is housed in a QFN-68 package and functions reliably across a wide operating temperature range from -40 °C to +105 °C.

Feature Summary

• Supports Qi2.x and Qi v1.3.2 wireless charging protocols with integrated Foreign Object Detection (FOD).
• Includes built-in USB-PD sink functionality for efficient power management and source compatibility.
• Configurable architecture allows adaptation for various consumer and industrial transmitter applications.

Applications

• Consumer electronics wireless charging pads
• Industrial equipment power transmitters
• Multi-charger stations sharing power sources

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific suffix 'QT' indicates tape and reel packaging if required for automated assembly. Check for end-of-life notifications as discontinuation status may affect long-term availability. Ensure compliance with RoHS directives for intended market deployment.

Selection Notes

Select this IC for designs requiring Qi2 certification alongside USB-PD integration. The QFN-68 package suits space-constrained PCB layouts. Evaluate thermal performance given the 105 °C maximum junction temperature. Consider the 15 W output limit when designing for higher-power fast-charging scenarios.
