The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algorithm to allow the negotiation of a power delivery contract with a source without MCU support (auto-run mode). PDO profiles are configured in an integrated non-volatile memory. The device supports dead battery mode and is suited for sink devices powered from dead battery state and requiring high power charging profile to be fully operational. Thanks to its 20 V technology, it implements high voltage features to protect the CC pins against short-circuits to VBUS up to 22 V and to support high voltage on the VBUS pins directly connected to the VBUS power path up to 28 V.
“This board allows you to use a USB-C power adapter as a power supply with a range of fixed voltages. It displays a list of the voltages and currents available from the adapter and allows you to select one …
“My first attempt in using USB-C adapters as a power source was met with great enthusiasm. It was just a breakout board for STUSB4500 autonomous USB-PD sink controller. It has since been picked up by Sparkfun with a …
