Overview
The STUSB4500LBJR is a standalone USB Type-C port controller designed by STMicroelectronics. This device is specifically tailored for 5 V-only sink devices, supporting up to 3 A (15 W maximum) of power. It is notable for its ability to operate in dead battery mode, allowing devices to be powered directly from the VBUS power source without any external software support. This feature enables quick application power-on and immediate charging process initiation. The STUSB4500LBJR monitors VBUS voltage and protects the application from incorrect SOURCE operations, ensuring safe and efficient power delivery.
