Overview

Description

As people increasingly seek ways to enhance home security, cloud-connected doorbells allow users to monitor their front door in real time. These devices provide instant alerts and access to live video feeds whenever someone approaches, enabling users to view live-stream video, take pictures, and check system status for enhanced security, convenience, and smart home integration.

This cloud-connected video doorbell design features an integrated battery charger, power management IC (PMIC), and Wi-Fi SoC, ensuring unmatched low-power consumption. This allows for continuous connectivity from the battery for extended periods, even if the line voltage is disconnected. The design utilizes a high PSRR video sensor PMIC to deliver clean power to the image sensor, ensuring the best possible image quality. It also includes system housekeeping functions such as secure Software Update Over-the-Air (SUOTA), power and battery monitoring, and more.

System Benefits​:

  • Ultra-low system power consumption for extended battery life while maintaining Wi-Fi connectivity.
  • Flexible, highly integrated, and optimized power supply scheme.
  • Multiple certified ultra-low power Wi-Fi modules are available to simplify design and shorten time to market (TTM).
  • Operates with and without a Wi-Fi connection.
  • Best achievable picture quality due to low noise and high PSRR video sensor PMIC.
