2.5A Output Current IGBT Gate Drive Optocoupler
Description
The SG8020 is an optically coupled 2.5A Output Current Gate Driver, designed to drive most 1200V / 100A IGBTs and MOSFETs. It is intended for driving high power IGBTs and MOSFETs used in motor control inverter applications.
The circuit consists of an infrared input LED optically coupled to an integrated circuit which utilizes a high speed driver.
The SG8020 comes standard in a miniature 8 pin DIP package.
