CT350 2.5A MOSFET/IGBT Gate Driver Optocoupler Features • Peak Output Current : IOP = ±2.5A (max) • Threshold Input Current: IFLH = 5 mA (max) • Common mode transient immunity : ±20kV/µs Description The CT350 consists of a GaAsP LED optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving ） power IGBTs and MOSFETs used in motor control (min • inverter applications. The high operating voltage Under voltage lock out (UVLO) protection with range of the output stage provides the drive hysteresis • voltages required by gate controlled devices. Pb free and RoHS compliant. Applications • Isolated IGBT/Power MOSFET gate drive • Industrial Inverter • AC brushless and DC motor drives • Induction Heating Package Outline Schematic Note: Different lead forming options available. See package dimension.
