onsemi / Fairchild FOD8314 栅极驱动光电耦合器
仙童 FOD8314 栅级驱动光电耦合器是 1.0A 输出电流栅极驱动光电耦合器，能够驱动中等功率 IGBT/MOSFET。它们对用于电机控制逆变器应用和高性能功率系统中的功率 IGBT 和 MOSFET 的快速开关驱动，是理想的选择。FOD8314 系列采用加长的封装，达到 8mm 爬电距离和电气间隙 (FOD8314T)。
The onsemi / Fairchild FOD8314 series has an optimized IC design that achieves reliable high-insulation voltage and high-noise immunity. They consist of an Aluminum Gallium Arsenide (AlGaAs) Light-Emitting Diode (LED) optically coupled to an integrated circuit with a high-speed driver for the push-pull MOSFET output stage.
The device is housed in a stretched body, 6-pin, small outline, plastic package.
