MPR031EPR2 Description

Short technical summary and product information.

The MPR031EPR2 by NXP Semiconductors is a proximity capacitive touch sensor controller designed for modern user interfaces. It replaces traditional mechanical buttons, offering enhanced reliability and energy efficiency.

 

This controller supports up to three touch pads and communicates via the I²C protocol. It is optimized for managing two electrodes with interrupt functionality or three electrodes without interrupt. The device operates within a voltage range of 1.71V to 2.75V and features a low supply current of 43µA.

 

The MPR031EPR2 is suitable for various low-power, handheld electronic products, including Bluetooth headsets, mobile phones, multimedia players, and remote controls. It is available in an 8-UFDFN package and operates across a temperature range of -40°C to +85°C.

 

Key features include continuous independent auto-calibration for each electrode, separate touch and release thresholds for hysteresis, and an optional IRQ output for status changes. This makes it a flexible component for designing intelligent systems and advanced user interfaces.
