STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, successfully held its first Industrial Summit at the Grand Hyatt Luohu Shenzhen, China, on May 29. As a high-profile event and technology showcase, ST’s Industrial Summit 2019 brought together key industry leaders, medium and small enterprises, partners, and industry associations from the wide-ranging and highly fragmented industrial market to explore and push the frontiers of smart innovation in Motor Control, Power and Energy, and Automation.

The summit packed plenty of highlights and received a lot of attention from the industry. The estimated number of participants in the summit was 500, however, the actual number of visitors has reached over 650.

ST showcased STUSB4500, 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.

ST also showcased a USB PD fast charging application based on STUSB4710 (SOURCE) and STUSB4500 (SINK). According to the power profile provided by the STUSB4710, the STUSB4500 will dynamically negotiate to accept 9V or 15V. In addition, a constant 5V output can be obtained through a DC/DC connected to VBUS. This 5V output supplies power to the entire system via the USB-A port.

ST also had the STUSB1700, an IC controller on display. It is fully compliant with the USB Type-C cable and connector specification (rev. 1.2), which addresses 5 V USB Type-C port management on the host side. It is fully autonomous and allows the advertising of the current capability to be managed by external pins. It is suited to implement power sharing capabilities, or external temperature protection mechanism with current capability adjustment.
