MPR031 MPR032
(I2C) Capacitive Touch Sensor Controller
The MPR03X is an Inter-Integrated Circuit Communication 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 Switch Replacements Touch Pads PC Peripherals MP3 Players Remote Controls Mobile Phones Lighting Controls
