ISP1109
USB transceiver with carkit support
8.
Modes of operation
The ISP1109 supports four types of modes:
Power modes
Serial control modes
USB modes
Transparent modes.
8.1 Power modes
8.1.1
Normal mode
In this mode, both V
CC
and V
CC(I/O)
are connected and their voltage levels are within the
operation range (V
CC
≥
3.0 V, V
CC(I/O)
≥
1.65 V, V
CC(I/O)
≤
V
CC
).
There are three levels of power saving schemes in the ISP1109:
Active power mode: Power is on; all circuits are active.
USB suspend mode: To reduce power consumption, the USB differential receiver is
powered off.
Power-down mode: Set by writing logic 1 to bit PWR_DN of the Mode Control 2
register. The clock generator and all biasing circuits are turned off to reduce power
consumption to the minimum possible; typically I
CC
is less than 20
μ
A. For details on
waking up the clock, see
Section 10
.
8.1.2
Disable mode
In disable mode, V
CC(I/O)
is cut-off and V
CC
is powered. In this mode, the ISP1109 is in
Power-down state, if V
BUS
is below SESS_VLD threshold (0.8 V to 2.0 V).
When V
CC
is below threshold V
th(ISET)
, pin ISET will remain at the LOW level.
When V
BUS
> V
th(svc)
and V
CC
rises above V
th(ISET)
, the ISP1109 will output HIGH on
pin ISET, if any of the following conditions is detected:
Voltage on pin ID is greater than V
th(ID_FM)
DP and DM are single-ended one (SE1).
If the preceding condition is detected, pin ISET will be asserted within 1.5 ms when V
CC
rises above V
th(ISET)
.
The USB differential driver will be set in three-state as long as V
CC(I/O)
is lost. The DP
pull-up resistor (R
UP(DP)
) will be disconnected from the DP line. The DP weak pull-up
resistor (R
weakUP(DP)
) will be connected if the V
BUS
voltage is above V
th(svc)
.
8.1.3
Isolate mode
In isolate mode, V
CC
is cut-off and V
CC(I/O)
is powered. In this mode, the ISP1109 will drive
stable level to all digital output pins, and all bidirectional digital pins will be set in
three-state.
Table 10
shows a summary of power modes.
