7.7 Audio switches
The audio switches provide low impedance path for analog audio signals to be multiplexed
on the DP and DM lines, or loopback between the MIC and SPKR lines.
There are five analog switches that are controlled by register bits. The impedance of the
switches will be between 50
and 150
.
Table 5
shows the relation between the control
bits and the switches.
Figure 5
shows the audio switches.
7.8 ISET detector
The ISET detector will set the ISET pin HIGH when either of the following conditions is
met:
ID > V
th(ID_FM)
, V
CC
> V
th(ISET)
and V
BUS
> V
th(svc)
DP and DM SE1 detected, V
CC
> V
th(ISET)
and V
BUS
> V
th(svc)
.
The DP and DM SE1 detector will time the length of the SE1 condition. The timer value is
programmable using register bit TMR_SE1. The timer ranges from 0 ms to 15 ms, with
1 ms interval.
The ID > V
th(ID_FM)
detector, and the SE1 detector (with timer) requires bias current.
In Power-down mode, the bias current is turned off to minimize current I
CC
. The bias
current needs to be enabled so that the ISET detector can function as described earlier.
If the Power-down is because V
CC(I/O)
is disconnected, the bias will be enabled if the
V
BUS
voltage goes above the SESS_VLD threshold.
