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.

FEATUREs
• 8 µA supply current with two electrodes being monitored with 64 ms response time and IRQ enabled
• Compact 2 x 2 x 0.65 mm 8-lead µDFN package
• Supports up to 3 touch pads
• Only one external component needed
• Intelligent touch detection capacity
• 4 µA maximum shutdown current
• 1.71 V to 2.75 V operation
• Threshold based detection with hysteresis
• I2C interface, with optional IRQ
• Multiple devices in a system allow for up to 6 electrodes (need MPR032 with second I2C address)
• -40°C to +85°C operating temperature range

Implementations
• Switch Replacements
• Touch Pads

Typical Applications
• PC Peripherals
• MP3 Players
• Remote Controls
• Mobile Phones
• Lighting Controls
