6.3.8.2
6.3.8.2.1
The cases A and B of the Figure provide the schematic arrangement of QTouch Group A/B and
Autonomous QTouch Sensors. In option A, Resistive drive is enabled on SNSK line. In case B,
Resistive drive is disabled on the SNSK line and in this case, it is recommended to use 1kOhm
resistors on SNSK Line external to the UC3L device.
6.3.8.2.2
In order to prevent interference from the 50 or 60 Hz mains line the CAT can optionally trigger
QTouch Group A/B and Autonomous QTouch acquisition on the external SYNC input signal. The
SYNC signal should be derived from the mains line and the acquisition will trigger on a falling
edge of this signal. The SYNC pin usage in the Internal Discharge mode scenario is shown in
case C. For QTouch method SYNC pin options Refer to
