USB4S012

UNISONIC TECHNOLOGIES CO., LTD USB4S012 Preliminary TVS 4-CHANNEL ESD SOLUTION FOR USB-HS/USB OTG/USB CHARGER INTERFACE  DESCRIPTION The U TC USB4S012 is a fo ur-channel ele ctrostatic disch arge (ESD) solution for USB charger or USB on-the-g o (OTG) interface. In many cell phone applications, the USB co nnector is the de facto communication port for external commu nications lik e hig h-speed data transfer, audio signal, charging, car-kit, etc. In order to support different interfaces, the USB port needs to handle different voltage levels. F or e xample, some chargers requ ire the V BUS port of the USB connector to handl e in e xcess of the n ormal V BUS voltage per USB specificat ions. T he U TC USB4S012 offers combina tions of two different clamp voltag es to ma tch the voltage toler ances 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 sp ace-saving pack ages with flo w-through pin mapping.  FEATURES * USB Signal Pins (D+, D–, ID) – 0.8-pF Line Capacitance – Tolerates 6V Signal * VBUS Line (VBUS) – 11-pF Line Capacitance – Tolerates 20V Signal * Flow-Through Pin Mapping for the High-Speed Lines Ensures Zero Additional Skew Due to Board Layout While Placing the ESD Protection Chip Near the Connector * Supports Data Rates in Excess of 480Mbps * Industri al T emperature Ra nge: – 40°C~85°C * Integrated ESD Clamps for D+, D–, VBUS, and ID Pins to Provide Single-Chip ESD P...
