Product overview

Description

The STWLC99 is a highly integrated wireless power receiver suitable for applications delivering an output power up to 100W.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 integrated low-loss synchronous rectifier and low drop-out linear regulator, STWLC99 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 wireless transmitter up to 25W (coil dependent)

The device is housed in a Chip-Scale Package to fit real-estate applications with reduced BOM count.
