The MVCTCH01 ASIC is an ultra-low power and high-sensitivity 8-channel capacitive touch interface that is designed to be easily integrated with capacitive touch pads. Ultra-low power operation is achieved by using a novel capacitive-to-digital converter, making it suitable for battery powered and portable devices.
The chip supports a low-power sleep mode, a scanning mode where the chip periodically scans the input channels for touch events at programmable intervals, and an active mode where the chip always scans the input channels.
