Power Supply Configurations and Options
The three modes of power supply operation are:
Normal Mode: Regulated Output and Regulator Bypass
1.
2.
In both cases, for normal mode, the V
dent voltage source (1.65V to 3.6V) that is a function of
the external circuit configuration.
Sharing Mode: V
and V
D- terminals are 3-STATE and the USB1T1103 allows

Regulated Output: V
is connected to 5V (4.0V to 5.5V) and the internal
voltage regulator then produces 3.3V for the USB
connections.
Internal Regulator Bypass Mode: V
nected and both V
nected to a 3.3V source (3.0V to 3.6V).

lines. Internally the circuitry limits leakage from D+ and
D- terminals (maximum 10µA) and V
device is in low power (suspended) state. Terminals
Vbusmon and RCV are forced LOW as an indication of
this mode with Vbusmon being ignored during this state.
Disable Mode: V

this mode D+ and D- are 3-STATE and V
Impedance (switch is turned off). The USB1T1103 allows
external signals up to 3.6V to share the D+ and D- bus
lines. Internally the circuitry limits leakage from D+ and
D- pins (maximum 10µ A).
