UTC2000-I/MG

The USB Type-CTM Specification was introduced in August 2014 and substantially expands the capabilities of USB. The key new features include: New Connector - Smaller Form Factor - 24 Pins - Reversible Insertion Simplified Current Capability Marking - Resistor-divider implementation instead of DP/DM “handshake” The Microchip UTC2000 USB Type-C controller targets designers who wish to gain the benefits of the small, reversible form factor and elevated charging current abilities of a USB Type-C solution while minimally impacting the overall cost per port. The UTC2000 USB Type-C controller is a cost-effective, simple solution that facilitates rapid migration of legacy USB 2.0/3.0 designs to the USB Type-C connector. The UTC2000 controller is designed for USB 2.0/3.0 Downstream Facing Port (DFP) and Upstream Facing Port (UFP) applications and performs all of the necessary detection and control required for implementing a basic USB Type-C connector. The UTC2000 features ADCs that monitor the CC1 and CC2 pins of the USB Type-C receptacle to detect various connection events. In a DFP application, passive cables, powered cables, and USB audio adapters can all be detected. Controls for enabling a USB +5V port power switch, VCONN 5V active cable supply, and audio adapter enable are all included. Additional features include host enable control and overcurrent detection. In a UFP application, the UTC2000 detects a valid USB Type-C connection, the plug orientation, and the charging capability of the DFP. The UTC2000 also monitors VBUS to ensure a valid VBUS range and detected overcurrent. The UTC2000 can operate from a single 4.5V-5.5V supply and is available in commercial, industrial and extended temperature range options.
