产品概述

描述

The STWLC38 is a highly integrated wireless power receiver solution suitable for applications up to 15W. The chip has been designed to support Qi 1.3 specifications for inductive communication protocol, Base Power Profile and Extended Power Profile (BPP, 5W max, EPP 15W max).
The STWLC38 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.
STWLC38 features embedded RRAM (Resistive RAM) non-volatile memory to enable I2C interface customization and support of proprietary communication and charging protocols
Additional firmware patching also improves the application flexibility of STWLC38.
STWLC38 is also capable of operating in Tx mode to transmit power to charge other devices, the output power can be up to 5W depending on the coil used.
The STWLC38 is housed in a Chip-Scale Package to fit real-estate sensitive applications like wearable devices.
