SG8080
SG8080 is IGBT Gate Drive Optocoupler manufactured by Solid State Optronic.
Description
The SG8080 is an optically coupled 2A 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 SG8080 es standard in a miniature 8 pin DIP package.
