The FSA881 is a high-performance switch featuring automatic switching and accessory detection for a USB port. The FSA881 allows sharing of a common USB port to pass USB data, as well as factory programmability. In addition, the FSA881 integrates accessory detection of devices such as USB chargers and factory data cables. The FSA881 can be programmed for manual switching or automatic switching of data paths. VBUSIN has 28V over-voltage tolerance. The difference between the FSA881 and the FSA881 is that FSA880 JIG output is an open-drain, active-LOW output, while FSA881 JIG is an active-HIGH, CMOS output.
