Touch chip applied in the field of intelligent door lock

The touch screen is introduced into the interaction of intelligent door lock to make the user experience of intelligent lock safer, more convenient and more personalized. The keyboard arrangement position can be changed randomly to truly realize password anti peeping; You can also set personalized themes according to your preferences.

With the continuous development of touch technology, the reliability and practicability of touch chip will be further improved. At present, the integration of touch chip has become higher and higher. Touch chip can be used as both main MCU and touch key, which makes the cost performance of touch chip higher and lower. Therefore, the application of touch chip will be more and more widely.

Capacitive inductive touch chip no longer requires human body to directly contact metal objects, which can completely eliminate potential safety hazards. It can be used even if people wear gloves, and is not affected by dry and humid weather, human resistance change and so on. It is more convenient for us. At present, there are two kinds of touch chips, one is resistive, the other is capacitive. Because of its higher reliability, capacitive is more widely used.

High resolution touch detection module and special signal processing circuit are integrated in the capacitive touch chip to ensure that the capacitive touch chip has sensitive automatic recognition and tracking function to environmental changes. Capacitive touch chip must also meet the high experience requirements of users in complex applications, such as stability, sensitivity, power consumption, response speed, waterproof, operation with water, anti vibration, anti electromagnetic interference and so on. In order to facilitate the user to independently control the sensitivity of the touch key in the application, the capacitive touch chip is also specially set with the sensitivity control bit.

The capacitive touch chip MTC series developed by Shenzhen Jerry Microelectronics Technology Co., Ltd. has the function of automatic sensitivity calibration, which is very suitable for battery powered electronic products. Such low power consumption makes your products more energy-saving and environmental friendly. The strong anti-interference touch IC is equipped with anti-power interference (different switching power supplies, basically the same sensitivity) and anti fast transient group pulse interference (EFT > 4KV), which meets the national class a standard.

Antistatic interference meets the requirements of national first-class standards and is resistant to RF interference. At the same time, it also has sensitivity automatic calibration function, power mutation suppression function, touch effective output time limit function, multi key simultaneous suppression function and combined key function. Some models also have backlight driving signal and buz driving signal. Provide touch dimming chip, complete dimming scheme and constant current drive IC for LED table lamp.

MTC series touch chip can provide up to 16 touch keys. MTC series touch chip is used for a wide power supply voltage range of 2.2V to 5.5V. Winmicro capacitive touch chip MTC series touch chips are mainly used in:

Security: intelligent door lock, visual doorbell, access control machine, etc

Household appliances: refrigerator, air purifier, air conditioner, washing machine, microwave oven, etc
