Product Overview

The MPR031EPR2 is a low voltage proximity capacitive Touch Sensor Controller. The inter-integrated circuit communication (I²C) driven touch sensor controller features optimized to manage two electrodes with interrupt functionality or three electrodes with the interrupt disabled. It can accommodate a wide range of implementations due to increased sensitivity and a specialized feature set. An I²C interface communicates with the host controller at data rates up to 400kbps. The interrupt output is a multiplexed with the third electrode output, so using the interrupt output reduces the number of electrode inputs to two. The MPR03X includes three levels of input signal filtering to detect pad input condition changes due to touch without any processing by the application.
  • Supports up to 3 touch pads
  • Intelligent touch detection capacity
  • 4µA Maximum shutdown current
  • Threshold based detection with hysteresis
ESD sensitive device, take proper precaution while handling the device.
