STWLC98中文资料符合Qi标准的电感式无线充电器电源接收器，适用于70W应用数据手册ST规格书

描述 Description

The STWLC98 is a highly integrated wireless power receiver suitable for applications delivering an output power up to 70W.The chip has been designed to support Qi 1.3 specifications for inductive communication protocol with extended power profile (EPP) and proprietary ST Super Charge(STSC) protocol for fast charging.

With integrated low-loss synchronous rectifier and low drop-out linear regulator, STWLC98 achieves high efficiency with low power dissipation.

Through 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, capable of transmitting up to 15W of power (depending on the coil used)

Chip-Scale Package and low bill of materials (BOM) count make it very suitable for compact applications.
