Quan Sheng electronic touch-chip QT1696 strong anti waterproof touch IC

Six-channel capacitive touch buttons chip chips Overview: QT1696 is an interference with the super, super waterproof 6-channel capacitive touch sensing chip can operate at different frequencies of switching power supply systems, and RC drop in non-isolated voltage power supply system and fully consistent sensitivity under the premise of appropriate sensitivity, splashing water overflow, flooding the touch-sensitive area will not lead to malfunction, even when water flooded into the film to be more than one sensor for normal touch operation In no case plus filter inductor can go through more than 4KV group pulse interference electrical fast transient test, interference during normal touch operation, the sensitivity is not reduced, not drift, it can also resist up to 5W walkie-talkie radio frequency interference, system With advanced automatic sensitivity calibration, sensitivity automatic compensation, work environment mutation suppression, to provide a flexible and easy way sensitivity adjustment, is widely ...... Features: ※ 3V-5.5V wide voltage ※ 3V power supply system under consuming only 1mA ※ ESD> 6KV, EFT> 4KV appliance industry in line with the relevant standards ※ C / S conducted disturbance immunity test up to three types of 10V standard ※ provide four designated key combination, user extensions ※ stabilized power supply initialization can be completed within 0.3S and start touching the touch detection ※ long effective output limit, which prevents the output signal is locked ※ embedded voltage regulator chip, ensure power supply ripple interference is not caused by a malfunction ※ button press shake down time ≥60ms ??\ button release debounce time ≥40ms ※ super waterproof, water splashing, water diffuse, flooding does not malfunction, can normally touch operation ※ touch signals using BCD code / analog voltage output, no agreement to facilitate communication with the host MCU ※ unique power violently anti-drop function, power sudden sharp fall will not result in malfunction ※ extremely simple external circuit, the simplest application circuit requires only one super-tune the sensitivity of the capacitive ※ The EMC interference resistance, 5W talkie near the sensing plate continuous, intermittent emission is not malfunction ※ sensitivity with advanced auto-calibration feature, when the working environment changes can be quickly and automatically adapt ※ sensitivity automatic compensation, PCB Layout cause each sensor input channel line length is inconsistent, consistent sensitivity ※ SOP-16L small package pin wide range of applications: small appliances, kitchen appliances water dispenser, cooker hood, water heater and easy access to electronic products
