IGBT Drive
IGBT gate drive photocouplers (optocouplers) are optically coupled isolators containing a GaAlAs LED on the input side and a photo diode, signal processing circuit and power output transistor on the output side in a single chip. This coupler is designed specifically to provide high common mode transient immunity (CMR) and a high output current, and has an active miller clamp and high switching speed, making it ideal for driving IGBTs and MOS FETs.
