Overview
The STUSB4500QTR is a standalone USB Power Delivery (PD) sink controller developed by STMicroelectronics. This device is designed to manage power delivery up to 100 W (20 V, 5 A) and is particularly suited for applications requiring high power charging profiles, especially from a dead battery state. The STUSB4500QTR operates in auto-run mode, allowing it to negotiate power delivery contracts with a source without the need for a microcontroller (MCU). It supports dead battery mode and features integrated VBUS switch gate drivers, VBUS voltage monitoring, and short-to-VBUS protections on the CC pins up to 22 V.
