The PI3USB102E offers over voltage protection for the Y+/Y- pins to protect from shorts to VBUS (5V). When the voltage on Y+/Y-

exceeds VOVP, the voltage at M+/M- and D+/D- is clamped to VDSW within the time TOVP. For rise time of 75 ns (as per USB1.1 and

USB2.0 low-speed specifications), TOVP is typically 40 ns. TOVP is smaller for faster risetimes. For example, TOVP is typically 20 ns

for rise time of 5 ns.
