Power Supply Configurations and Options
The three modes of power supply operation are:
Normal Mode: Regulated Output and Regulator Bypass
1. Regulated Output: V
CCIO
is connected and V
CC
(5.0)
is connected to 5V (4.0V to 5.5V) and the internal
voltage regulator then produces 3.3V for the USB
connections.
2. Internal Regulator Bypass Mode: V
CCIO
is con-
nected and both V
CC
(5.0) and V
REG
(3.3) are con-
nected to a 3.3V source (3.0V to 3.6V).
In both cases for normal mode the V
CCIO
is an indepen-
dent voltage source (1.65V to 3.6V) that is a function of
the external circuit configuration.
Sharing Mode: V
CCIO
is only supply connected. V
CC
and
V
REG
are not connected. In this mode the D and D ter-
minals are 3-STATE and 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 ter-
minals (maximum 10
P
A) and V
CCIO
such that 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
CCIO
is not connected. V
CC
is con-
nected, or V
CC
and V
REG
are connected. 0V to 3.3V in
this mode D and D are 3-STATE and V
PU
is HIGH
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 10
P
A).
A summary of the Supply Configurations is described in
Table 4.
