STMicroelectronics STUSB4500

STUSB4500 & STUSB4500L are USB power delivery controllers that addresses 5 V-only sink devices up to 3 A (15 W max.) for STUSB4500 and sink up to 100 W (20 V; 5 A) for STUSB4500L.

STUSB4500 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.

STUSB4500 & STUSB4500L support dead battery mode and are suited for sink devices powered from dead battery state and requiring high power charging profile to be fully operational.

STEVAL-ISC005V1:

Evaluation board for the STUSB4500 USB power delivery controller

The STEVAL-ISC005V1 evaluation board is a ready-to-use USB PD sink based on STUSB4500. It handles the USB PD negotiation with a source to enable one or more charging paths. An L7985 device ensures step-down conversion from the negotiated VBUS sink input to output a 5 V regulated supply which optionally allows powering an MCU evaluation board or any other system.
