USB 2.0 Port Protection with Charger Detection

This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the

LOW period of the SCL signal, it must output the next data bit to the SDA line tr_max + tSETDAT = 1000 + 250 = 1250ns

(according to the standard-mode I

2C bus specification) before the SCL line is released.

2. Cb equals the total capacitance of one BUS line in pF. If mixed with high-speed devices, faster fall times are allowed

according to the I

2C specification.
