ST STUSB4500LBJR

The STUSB4500L is a USB Type-C controller that addresses sink devices.

This device supports dead battery mode and is suited for sink devices powered from dead battery state. It is able to operate without any external software support for quick application power-on and immediate charging process start. At type-C connection, the STUSB4500L seeks CC pin for SOURCE termination and monitors VBUS voltage in order to protect the application from an incorrect SOURCE operation. When VBUS is within the appropriate range, the STUSB4500L powers the application by closing the input switch. The available current advertised by the SOURCE is reported to the application in order to align the sinking current. Port status can be optionally monitored by the software through I²C interface.

Thanks to its 20 V technology, it implements high voltage features to protect the CC pins against short-circuits to VBUS.
