Description

chip(4.3x3.9mm)

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

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.

Tape and reel

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 wireless transmitter up to 15W (coil dependent)

Chip-Scale Package and low BOM count makes it very suitable for compact

applications.
