Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are disclosed for implementing a power sequencing technique implemented using circuitry for powering a chime that outputs audio in response to a trigger event. An integrated circuit of a video doorbell receives a first power signal from a source and generates a half-wave pulse for a power sharing sequence of the circuit, based on the first power signal. The generated half-wave pulse is interrupted and the circuit generates a second power signal that causes the chime to initiate outputting the audio. The second power signal corresponds to the first power signal and is generated in response to interrupting the half-wave pulse. The circuit resumes generating the half-wave pulse to power the chime using the power sharing sequence after causing the chime to initiate outputting the audio using the second power signal.
