STMicro's 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). Power data objects (PDO) profiles are configured in integrated non-volatile memory. The device supports dead battery mode and is suitable for sink devices powered from a dead battery state and requiring a 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.
