VBUS Range
VBUS = +5.0V, D+ D- Shorted
VBUS = +5.0V, D+ D- Shorted
VBUS = 0V or 5V VIN on D+ = 5V
VBUS = 0V or 5V VIN on D- = 5V
VBUS = +5.0V, Flag2 = LOW
Voltage Sweep through Upper
and Lower Trip Points
VBUS = +5.0V, Flag2 = LOW
Voltage Sweep through Upper
and Lower Trip Points
VBUS = +5.0V, IOH = -20µA
VBUS = +5.0V, IOL = 20µA
