STWLC04数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The STWLC04 is an integrated wireless power receiver suitable for wearable applications. The device is designed for 1-watt power transfer based on the Qi protocol, with digital control and precise analog control loops ensuring stable operation. The I2C interface allows a high degree of customization and settings can be stored in the embedded non-volatile memory.
The STWLC04 can deliver the output power in two modes: as a power supply with configured output voltage or as a simple CC/CV battery charger with configurable charging current, charging voltage and termination current. The STWLC04 can detect the external (wired) power supply connection and drive an external power switch.
