Isolated Self-Powered AC Solid State Relay with MOSFETs Reference Design

Description

The isolated self-powered AC solid state relay with MOSFETs reference design is a relay replacement that enables efficient power management for a low-power alternative to standard electromechanical relays. The galvanic isolation is implemented capacitively: creating a cost-efficient: reduced footprint solution for multiple relay replacement in thermostats and other similar equipment.
