USB Port 2:1 Switch with Accessory and Charger Detection

The FSA880 is a high-performance switch featuring automatic switching and accessory detection for a USB port. The FSA880 allows sharing of a common USB port to pass USB data, as well as factory programmability. In addition, the FSA880 integrates accessory detection of devices such as USB chargers and factory data cables. The FSA880 can be programmed for manual switching or automatic switching of data paths. VBUSIN 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.
