Image of STMicroelectronics STWLC98JR Inductive Wireless Charger Power Receiver STMicroelectronics' STWLC98JR is a highly integrated wireless power receiver suitable for applications delivering an output power of up to 70 W. The chip has been designed to support Qi specifications 1.2.4 and 1.3 for inductive communication protocol with Extended Power Profile (EPP) and proprietary ST Super Charge (STSC) protocol for fast charging.

With an integrated low-loss synchronous rectifier and low drop-out linear regulator, STWLC98JR achieves high efficiency with low power dissipation. Through the I²C interface, the user can access and modify the configuration parameters for customized applications. The final configuration parameters are stored in embedded Few Times Programmable (FTP) non-volatile memory and automatically retrieved at power-up.

The device can also operate as a wireless transmitter up to 15 W (coil-dependent). The chip-scale package and low BOM count make it very suitable for compact applications.
