With the USB Type-C Development Kit from Würth Elektronik eiSos, those looking to take advantage of the vastly expanded range of options offered by USB Type-C and USB Power Delivery in their projects have a convenient and immediate solution at hand: built from proven USB-Type C technology from STMicroelectronics, Würth Elektronik’s USB Type-C Development Kit is ready for immediate use in prototypes and represents a reference design for safe and flexible USB PD applications up to 100W.
USB Type-C connector is today being used by many devices. Whatever the final application is, there are many reasons for adopting USB-C connectors. Since it is reversible, it can be plugged into a device any which way. Able to carry up to 100 W charging power (from 5V/0.1A up to 20V/5.0A), it merges and is backward compatible with the functionality of both legacy Type-A and -B ports in a single one and even can change roles on the fly.
With the USB Type-C Development Kit, Würth Elektronik eiSos has relieved its customers of two of the biggest challenges in developing USB PD applications:
- A robust solution with embedded protection against short-circuit, overvoltage, overcurrent and electromagnetic interference ensured by using USB Type C connectors, inductive components and capacitors from Würth Elektronik eiSos and certified USB Power Delivery controllers from ST with built-in protection.
- A complete and ready-to-use solution with evaluation boards and a demonstration board for sink and source applications from 0,5W up to 100W. These boards can be used without any extra software or firmware for faster development time.
The USB Type-C Development Kit includes three assembled boards and a high current rating USB Type-C cable.
The first board is the 40W Source Evaluation Board with the STUSB4710 autorun controller and on-board DC/DC converter from ST. The STUSB4710 integrates all the digital and high-voltage analog circuitry needed to autonomously support full USB PD negotiation. It supports up to 5 Power Data Objects (PDO) and power-sharing applications thanks to its I²C interface. Typical applications are power-source applications such as AC adapters, power supplies, power hubs, smart plugs and DC-DC applications.
The second board is the 100W Sink Evaluation Board with the STUSB4500 autorun controller from ST. It allows straightforward migration from STD-B, micro-B or custom power plugs to a Type-C connector. This solution is ideal for automatically prompting a charging process – even if the battery is empty. The STUSB4500 supports up to 3 PDOs. Typical applications are electronic devices charged through USB Type-C connector.
The third board is the 100W Source Demo Board with the STUSB1602 – an analog front-end that is a companion chip of the STM32 microcontroller – and on-board DC/DC converter. The STUSB1602 provides up to 5 PDOs. Typical applications include power-source applications such as AC adapters, power supplies, power hubs, smart plugs and DC-DC applications.
