概述Description
群芯微QX3120 是一種輸出電流為2.5A 的柵極驅動光電耦合器,具有一個砷化鋁鎵(AlGaAs)的發光二極管,通過紅外光耦合到光敏集成電路。這種光電耦合器可驅動大多數的小功率IGBTs 和MOSFETs。在電機控制逆變器以及高性能電力系統應用中,非常適用于快速切換驅動功率IGBTs 和MOSFETs。
The QX3120 is a gate driven optocoupler with an output current of 2.5 A, with an AlGaAs LED, which is coupled to a photosensitive integrated circuit through infrared light. This optocoupler can drive most low-power IGBTs and MOSFETs. In the motor control inverter and high-performance power system applications, it is very suitable for fast switching drive power IGBTs and MOSFETs.
