Fully-integrated low-power mesh sensor protecting against enclosure tampering

Overview

The Mesh Sensor is a mixed-signal IP detecting the enclosure tampering by monitoring its resistivity level at multiple points.

Key Features

  • fully-integrated low-power mesh sensor
  • 16 multiplexed impedance sensing inputs (customized on request)
