Proximity Capacitive Touch
Sensor Controller
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
6 A supply current with two electrodes being monitored with
32 ms response time and IRQ enabled
Compact 2 x 2 x 0.65 mm 8-lead DFN package
Supports up to 3 touch pads
Only one external component needed
Intelligent touch detection capacity
4 A 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
