Description
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.
