The chip has been designed to support Qi 1.2.4 specifications for inductive communication protocol and Base Power Profile (BPP). The STWLC68 shows excellent efficiency performance thanks to the integrated low- loss synchronous rectifier and the low drop-out linear regulator: both elements are dynamically managed by the digital core to minimize the overall power dissipation over a wide range of output load conditions. Through the I2C interface the user can access and modify different configuration parameters, tailoring the operation of the device to the needs of custom applications. The configuration parameters can be saved in the embedded OTP memory and automatically retrieved at power-up, allowing the STWLC68 to operate as stand- alone device. The STWLC68 is housed in a Chip-Scale Package to fit real-estate solutions in wearable devices.
