The Photovoltage Output optocoupler is optically coupled to a high-voltage output photodetector circuit using an aluminum gallium arsenide infrared light-emitting diode as the input stage. The photodetector circuit consists of a high-speed photodiode array and a driving circuit.
It can be widely used for gate drive of power MOSFETs or IGBTs, and provides voltage sources for electronic circuits; Hualian provides optocouplers with packages of SOP4, DIP4/SMD4, DIP6/SMD6, DIP8/SMD8, etc.
Besides the common models in the market, Hualian also provides products with integrated overcurrent detection function in the category of optical voltage output photocouplers.
