Proximity Capacitive Touch

Sensor Controller

MPR03X OVERVIEW

The MPR03X is an Inter-Integrated Circuit Communication (I²C)

driven Capacitive Touch Sensor Controller, 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.
