Microchip Technology, Inc. Touch Screen Controllers MTCH6102T-I/MV

The Microchip MTCH6102 is a low-power projected capacitive touch controller designed to facilitate the integration of touch interfaces in various applications. It supports up to 15 channels, enabling functionalities such as taps, swipes, and scrolling on touch pads and screens. The device is suitable for cost-sensitive and low-power applications, making it ideal for wearable devices, remote controls, gaming devices, and home automation systems. The MTCH6102 features a configurable I¬=C communication interface with a maximum speed of 400 kbps and supports both polling and interrupt schemes. It operates within a voltage range of 1.8V to 3.6V and can function in temperatures from -40¬8C to +85¬8C. The controller can handle sensor sizes up to 120 mm and is compatible with various sensor types, including PCB, film, glass, and flexible printed circuits. With a touch performance of over 200 reports per second and 12-bit resolution, the MTCH6102 also includes features such as gesture detection, self-capacitance signal acquisition, and multiple built-in filtering options. Its power management capabilities allow for configurable sleep and idle modes, with standby current typically below 500 nA and active mode current under 12 ¬µA. The device is packaged in a 28-pin UQFN format, making it suitable for compact designs.
