Professional supply Integrated circuit IC STUSB4500BJR Standalone USB PD sink controller with short-to-VBUS protections

Product Descriptions

The STUSB4500 is a USB power delivery controller that addresses sink up to 100 W (20 V; 5 A). 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.

The STUSB4500 is a USB Type-C™ and power delivery controller IC for sink applications. It is able to negotiate a power delivery contract with a source without MCU support (auto-run mode). It relies on proprietary algorithms

and configurable PDO (power data objects) thanks to an integrated non-volatile memory. It supports dead battery mode to allow a system to be powered from an external source directly. Combined with its capability to negotiate directly a power contract, the STUSB4500 is the ideal controller device for autonomous systems requiring high power charging profile to be fully operational.

The STUSB4500 major role is to:

1. Detect the connection between two USB Type-C ports (attach detection)

2. Establish a valid source-to-sink connection

3. Determine the attached device mode: source or debug accessory

4. Resolve cable orientation and twist connections to establish USB data routing (MUX control)

5. Negotiate a USB power delivery (PD) contract with a PD capable source device

6. Configure the incoming VBUS power path and the charging paths accordingly

7. Monitor the VBUS power path and manage the VBUS voltage transitions

8. Handle the high voltage protections

The STUSB4500 also provides:

• Dead battery mode

• PDO (power data object) customization through NVM

• Internal and/or external VBUS discharge paths

• Dual high power charging path support

• Debug accessory mode detection

• Customization of the device configuration through NVM to support specific applications
