ISP1109
USB transceiver with carkit support
The DP pull-down resistor (R
DN(DP)
) is connected to the DP line, if bit DP_PULLDOWN in
the Resistor Control register is set.
The DM pull-down resistor (R
DN(DM)
) is connected to the DM line, if bit DM_PULLDOWN
in the Resistor Control register is set.
7.5 Power block
The built-in DC-DC regulator conditions the input power supply (V
CC
) for use in the core of
the ISP1109.
When V
CC
is greater than 3.6 V, the regulator will output 3.3 V
±
10 %. When V
CC
is less
than 3.6 V, the regulator will be bypassed and pin REG3V3 will be shorted to pin V
CC
.
The output of the regulator can be monitored on pin REG3V3. A capacitor (0.1
μ
F) will be
connected to pin REG3V3.
7.6 Carkit DP interrupt detector
The carkit DP interrupt detector is a comparator that detects the carkit interrupt signal on
the DP line in analog audio mode. Bit DP_INT will be cleared (set to logic 0), if the voltage
level on the DP line is below the carkit interrupt threshold V
thPH(DP)L
(0.4 V to 0.6 V).
The carkit interrupt detector is enabled in audio mode only (bit AUDIO_EN = 1).
