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 rectifier circuit configured to generate a first signal based on a power source and a first switch coupled to the rectifier circuit. The first switch is configured to provide, based on the first signal, a first DC voltage signal during a first operating mode where the doorbell receives input that triggers actuation of the chime in response to detection of the entity. The circuit includes a second switch coupled to the rectifier circuit and the first switch. Based on the first signal, the second switch provides a second DC voltage signal during a second operating mode where the chime outputs the audio based on the input that triggers actuation of the chime in response to detection of the entity.
