Abstract: A circuit is described for powering a video doorbell in signal communication with a chime that outputs audio. The circuit includes a switch coupled to a set of input power wires that supply power to the circuit from a source. The switch is operable to switch between: i) a first path of the circuit that supplies power to the video doorbell using the input power wires and ii) a second path of the circuit that supplies power to the chime using the input power wires. The circuit includes a controller that controls the switch to iteratively switch between the first path and the second path based on a timing metric. In response to detection of an object by the video doorbell, the iterative switching between the first path and the second path concurrently powers the video doorbell and the chime without relying on battery power at the video doorbell.

Abstract: A circuit is described for powering a chime that outputs audio in response to detection of an entity by a video doorbell. The circuit includes a power source for generating a first signal. A first switch is coupled to the power source. The first switch is configured to provide, in response to the first signal, a first direct-current (DC) voltage signal during a first operating mode where the video doorbell receives an input that triggers actuation of the chime in response to detection of the entity. A second switch is coupled to the power source and the first switch. The second switch is configured to provide, in response to the first signal, a second DC voltage signal during a second operating mode where the chime outputs the audio in response to the input that triggers actuation of the chime in response to detection of the entity.

Abstract: A circuit is described for powering a video doorbell in signal communication with a chime that outputs audio in response to a button on the video doorbell being pressed. The circuit includes a rectifier circuit configured to: i) receive a first voltage signal generated based on a power source and ii) generate a second voltage signal based on the first voltage signal. The circuit includes a boost circuit that generates a high-voltage direct-current (DC) signal for charging a capacitor without generating a peak current that triggers a particular noise output from the chime. The circuit also includes a converter circuit that generates a low-voltage power signal based on the high-voltage DC signal and a charge stored at the capacitor. The low-voltage power signal is for powering a plurality of components of the video doorbell.

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.
