Microchip MXT288UD Touch Controller
Low power mode and inside and outside the vehicle, etc.
Provides weather-resistant operation and glove touch detection features


Microchip expanded its maXTouch product family on the 30th by releasing two MXT288UD touch controllers.

The MXT288UD-AM and MXT144UD-AM devices provide low-power mode, weather-resistant operation, and glove touch detection capabilities for multifunctional displays, touchpads, smart surfaces, etc., used in various mobility applications.

Both devices can be placed both inside and outside the vehicle, such as on door handles, car doors, electronic mirrors, control knobs, steering wheels, seats, and armrests. Tier 1 suppliers can reduce board space by 75% with the MXT288UD family, which is available in a 7×7mm VQFN56 package.

The low-power touch mode built into the MXT288UD family consumes less than 50µA of power and responds instantly to the driver's touch even when the display is off, so as not to disturb the driver during power-saving mode or night driving. The system is activated when there is a touch response anywhere on the touch surface.

In addition, with a high signal-to-noise ratio and Microchip's unique differential mutual acquisition technology, multiple fingers wearing gloves of various materials and thicknesses can be detected simultaneously. Because it has weather resistance that allows it to operate in various climates, it is suitable for vehicles with many surfaces exposed to the outside, such as motorcycles.

The MXT288UD product family, a turnkey solution, was developed according to the A-SPICE process and provides verified firmware that has obtained AEC-Q100 certification. Based on this, automotive manufacturers can easily integrate it into existing systems, reduce risk, and accelerate time-to-market.
