STUSB1700 USB Type-C source controller with high voltage protections Datasheet - preliminary data Applications Automotive: USB car chargers (single and dual port), 12 V car chargers accessories, infotainment systems Smart plugs, wall adapters and chargers Features Power hubs and docking stations Single power role support: source mode Notebook host port Type-C attach and cable orientation detection LCD monitors & TV Configurable current advertising through Power bank external control pins Any Type-C source device Configurable start-up profiles through NVM Integrated V voltage monitoring and Description BUS discharge path The STUSB1700 is an IC controller, fully Short-to-V protections on CC pins (22 V) BUS compliant with the USB Type-C cable and and V pins (28 V) BUS connector specification (rev. 1.2), which High and/or low voltage power supply: addresses 5 V USB Type-C port management on V = 3.0 V 5.5 V SYS the host side. It is fully autonomous and allows V = 4.1 V 22 V DD the advertising of the current capability to be Integrated power switch for V supply: CONN managed by external pins. It is suited to programmable current limit up to 600 mA implement power sharing capabilities, or external overcurrent, overvoltage and thermal temperature protection mechanism with current protection capability adjustment. undervoltage lockout The STUSB1700 is designed for a broad range of Integrated V discharge path applications and can handle the following USB CONN Type-C functions: attach detection, plug Accessory mode support orientation detection, host to device connection, 2 I C interface and interrupt (optional connection V support, and V configuration. Thanks CONN BUS to MCU) to its 20 V technology, it implements high voltage Temperature range: -40 C up to 105 C protection features against short-circuits to V BUS up to 28 V. The device is fully customizable ESD: 4 kV HBM - 1.5 kV CDM thanks to an integrated non-volatile memory. AEC-Q100 qualified Certification test ID 1100100 Table 1.
