Product overview
Description
The STWLC88 is a highly integrated wireless power receiver solution suitable for applications up to 50W. The chip has been designed to support the latest Qi specifications for inductive communication protocol with Extended Power Profile (EPP) and proprietary STSuperCharge (STSC) protocol for fast charging.
This solution requires low external BOM count. Because of the integrated low impedance synchronous rectifier and low drop-out linear regulator, STWLC88 achieves high efficiency and low power dissipation.
The STWLC88 features embedded FTP non-volatile memory to enable I2C interface customization and support of proprietary communication and charging protocols.
The STWLC88 is also capable of operating in transmitter (Tx) mode to share power for charging other devices with the output power up to 12W depending on the coil used.
The Flip Chip (4.07 x 4.49 mm) and low BOM count makes it very suitable for very compact application.
