The STUSB03E is designed to provide USB connectivity in mobile systems where available system
supply voltages are not able to satisfy USB requirements. The STUSB03E can operate down to supply
voltages of 1.6V and still meet USB physical layer specifications. As shown in the circuit above, the
STUSB03E takes advantage of the USB supply voltage, V
voltage, V
controller. Internal circuitry provides translation between the USB and system voltage domains. V
typically be the main supply voltage rail for the controller.
In addition, a 3.3V, 10% termination supply voltage, V
be disabled or enabled under software control via the CON input. This allows for software-controlled
connect or disconnect states. A 1.5K resistor is required to be connected between this pin and the D- line
when operating in low speed mode. In full speed mode either an internal pull-up resistor or an external
one connected between V
