Overview

Video doorbells are getting smarter, and our integrated circuits and reference designs will help you differentiate your next design. Advanced features such as audio/video streaming, wireless connectivity and sensing will help you quickly create an innovative doorbell design.

Design requirements

Next-generation video doorbell designs often require:

  • Highly-efficient power tree from AC input to the point of load.
  • Higher thermal efficiency due to small form factor and no air vents.
  • Addressing battery drain due to overall leakage current and load sharing during chime operation.
  • Address false chiming triggered by peak currents during system operation.
  • Stable battery operation across temperature range, especially negative temperature.
