QTC18X series capacitive touch chip

QTC18X series capacitive touch IC [be conducted immunity EMC 10V full band through all the tests, C / S to normal operation, touch panel operation] water normally have superior anti-jamming, super water capacity of 8 Channel Capacitive touch sensing chip can operate at a different frequency of the switching power supply system as well as non-isolated power supply systems RC Buck and the sensitivity is fully consistent with the premise under appropriate sensitivity, splashing water overflow, flooding the touch panel will not trigger malfunction, even if the water flooded into the film to be more than one sensor for normal touch operation, no need to increase the inductance in the filter case can go through more than 4KV group pulse interference electrical fast transient test, can interfere with the normal process of touch operation, the sensitivity is not reduced, not drift, can also resist up to 5W walkie-talkie radio frequency interference, the sensitivity of the system with advanced auto-calibration feature, the sensitivity of the automatic compensation, work environment mutation suppression, providing a flexible, easy sensitivity adjustment method, applied very wide ......
