UNISONIC TECHNOLOGIES CO., LTD USB4S012 Preliminary TVS 4-CHANNEL ESD SOLUTION FOR USB-HS/USB OTG/USB CHARGER INTERFACE DESCRIPTION The UTC USB4S012 is a four-channel electrostatic discharge (ESD) solution for USB charger or USB on-the-go (OTG) interface. In many cell phone applications, the USB connector is the de facto communication port for external communications like high-speed data transfer, audio signal, charging, car-kit, etc. In order to support different interfaces, the USB port needs to handle different voltage levels. For example, some chargers require the VBUS port of the USB connector to handle in excess of the normal VBUS voltage per USB specifications. The UTC USB4S012 offers combinations of two different clamp voltages to match the voltage tolerances of the different signal interfaces using the common USB connector. The UTC USB4S012 conforms to IEC61000-4-2 (Level 4) ESD. The device is offered in space-saving packages with flow-through pin mapping.
