FSA880 / FSA881 - USB Port 2:1 Switch with Accessory and Charger Detection Features Description Switch Type 2:1 USB Automatic switching with Available Switch Mechanism Interrupt USB Data Cable Chargers (CDP, DCP, Travel Adapter, Accessory Detection Car Kit-CEA-936-A) Factory-Mode Cables USB FS and HS 2.0 Compliant Battery Charging 1.1 Compliant USB Charging Charger Detect, DCD, OVT (28V) UART RxD and TxD VBAT 3.0 to 4.4V Programmability I2 C ESD 15kV IEC 61000-4-2 Air Gap Operating -40C to 85C Temperature 16-Lead UMLP Package 1.8x2.6x0.55mm, 0.4mm Pitch FSA880 - Active LOW JIG Option FSA881 - Active HIGH FSA880UMX Ordering Information FSA881UMX The FSA88x is a high-performance switch featuring automatic switching and accessory detection for a USB port. The FSA88x allows sharing of a common USB port to pass USB data, as well as factory programmability. In addition, the FSA88x integrates accessory detection of devices such as USB chargers and factory data cables. The FSA88x can be programmed for manual switching or automatic switching of data paths. VBUS_IN has 28V over-voltage tolerance. The difference between the FSA880 and the FSA881 is that FSA880 JIG output is an open-drain, active-LOW output, while FSA881 JIG is an active-HIGH, CMOS output.
