The TDC1000QPWRQ1 digital touch controller combines supercapacitive touch and proximity sensing technologies in one digital solution with an integrated direct drive touch button. The digital touch sensing solution offers excellent proximity sensing performance and a stable touch button. It offers a broad range of possible applications and is ideal for creative mobile designs. This article provides an overview of the TDC1000QPWRQ1 application fields and working principles.

Application Fields

The TDC1000QPWRQ1 has the versatility to cover a broad range of applications ranging from home appliances such as air conditioners, refrigerators, and washing machines to electronic control panels for car infotainment and home entertainment systems. It is also applicable for industrial and medical equipment. As an alternative to mechanical switches, the TDC1000QPWRQ1 can work as slider switches, proximity sensing and integrated touch buttons. Other potential applications include human-machine interface (HMI) for gaming, automation, fitness and healthcare products.

Working Principle

The TDC1000QPWRQ1 uses a patented SuperCapacitive touch sensing technology. The sensor works as two plates with a dielectric in between. When an electrostatic field is created between them, the electrical current flowing through them is used as an energy source and converted into digital signals. That helps with detecting the presence of a finger, stylus, and even body parts. The digital signals are then used to determine the location of the user.

The TDC1000QPWRQ1 also utilizes an integrated direct drive touch button. This allows the user to experience a natural and easy press with a higher touch sensitivity. The integrated direct drive touch button is much more shock and vibration resistant than traditional capacitive touch buttons.

Additionally, the TDC1000QPWRQ1 utilizes an on-device temperature temperature sensing that allows for pulse width modulation (PWM) and adaptive sampling rate control to optimize power consumption for long battery life. The device also has low power consumption, with a sleep mode current of 1uA and a wakeup time from sleep of less than 10ms.

Conclusion

The TDC1000QPWRQ1 is a versatile digital touch sensing solution that offers many different applications and excellent proximity sensing performance. Its supercapacitive touch sensing technology and integrated direct drive touch button allow for a more natural user experience. The device also features low power consumption, a shock and vibration resistant touch button, and on-device temperature sensing. All of these features allow for creative and advanced mobile designs.
