Overview

Elevator calling button operating panels are adding new features and capabilities including capacitive touch human machine interface (HMI), people counting and wireless communication. Our reference designs and integrated circuits help you understand and integrate these technologies into your design.

Design requirements

Modern elevator calling button operating panel designs require:

  • Noise-tolerant capacitive touch HMI.
  • Wireless communication.
  • Faster, more robust wired communication solutions, such as CAN.
