DEMOMPR031

The DEMOMPR031 is an MPR031 inter integrated circuit communication (I2C) driven capacitive touch sensor controller demo board, 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.

• 6µA supply current with two electrodes being monitored with 32ms response time and IRQ enabled
• Compact 2mm x 2mm x 0.65mm 8led µDFN package
• Supports up to 3 touch pads
• Only one external component needed
• Intelligent touch detection capacity
• 4µA maximum shutdown current
• 1.71V to 2.75V operation
• Threshold base detection with hysteresis
• I2C interface, with optional IRQ
• Multiple devices in a system allow up to 6 electrodes (need MPR032 with second I2C address)
