The WLC1115-68LQXQ from Infineon Technologies is a 15 W Wireless Charging Transmitter IC that supports WPC Qi and other proprietary specifications. It has an input voltage from 4.5 V to 24 V. This transmitter IC has a highly programmable and integrated USB-PD link solution that supports both the latest USB-PD 3.0 version as well as USB-PD legacy charging protocols such as QC 2.0/3.0 and AFC. It is designed using a 32-bit ARM Cortex-M0 processor and consists of gate drivers, buck converter controller, Q-factor detector, and FSK modulator. This transmitter IC supports various analog and digital peripherals such as ADC, PWMs, and timers.
The WLC1115-68LQXQ offers over-current protection (OCP), over-voltage protection (OVP), and an internal temperature sensor to avoid over-heating of the IC. This RoHS compliant wireless transmitter is available in a surface-mount package that measures 8 x 8 x 0.65 mm and is ideal for high speed charging support, docking stations, smart speakers, portable accessories, wireless charging pads for extended power profile (EPP) 15 W, and basic power profile (BPP) (5 W) and furniture/home goods applications.
