Product overview
Description
The STWLC38JRM is a highly integrated wireless power receiver solution suitable for applications up to 15 W.
The STWLC38JRM 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.
STWLC38JRM features embedded RRAM (Resistive RAM) nonvolatile memory to enable I²C interface customization and support of proprietary communication and charging protocols.
Additional firmware patching also improves the application flexibility of STWLC38JRM.
The STWLC38JRM is housed in a chip scale package to fit real-estate sensitive applications like wearable devices.
