MTCH105-I/ST

1. Technical Introduction of MTCH105-I/ST

MTCH105-I/ST is a low-power capacitive touch sensor designed for devices that need a larger capacitive detected range. It is a cost-effective brand-new product, which combines the latest non-contact touch sensing technology with the lowest power consumption. It offers developers an excellent choice for sensing buttons, sliders and other touch objects, using a low-power capacitive design to maximise battery life.

The MTCH105-I/ST features a wide detection range of up to 10 mm, and its low power consumption allows it to be triggered when needed instead of relying on continuous sensing (which was the traditional approach).

The main features of the MTCH105-I/ST include:

• Ultra-low power consumption: As low as 10 nA standby current, and 2 mA maximum detect current
• High accuracy: With a detection range of up to 10 mm, it offers high accuracy
• Low noise immunity: The built-in low noise filter enables it to detect even faint touches
• Small form factor: It has a dimension of only 22.9 * 16 * 1.3 mm

2. Application Field and Working Principle

The MTCH105-I/ST can be used in a wide range of applications that require low-power, high-accuracy capacitive sensing. It is ideal for detecting buttons, sliders and other touch objects, and can be used on both touch screens and in consumer electronics.

The working principle of the MTCH105-I/ST is based on capacitive coupling. It works by detecting changes in the capacitance between a conductive plate and an object. When there is an object touching the plate, the capacitance changes, and the MTCH105-I/ST can detect this change.

The MTCH105-I/ST also has a low-noise filter that can be used to reduce interference from other sources. This filter helps it to detect even faint touches, making it more reliable and accurate.

3. Conclusion:

The MTCH105-I/ST is an ideal low-power, high-accuracy capacitive sensor for detecting buttons, sliders, and other touch objects. It has a wide detection range, low power consumption, and a low-noise filter to reduce interference. With its small form factor, it is ideal for consumer electronic products that need a capacitive touch sensor.
