The ACPL-P314/ACPL-W314 are gate drive optocouplers featuring a GaAsP LED coupled to a power output stage IC. They are ideal for driving power IGBTs and MOSFETs in motor control inverter applications, offering high operating voltage for gate control and sufficient output voltage and current for direct drive of medium to small power IGBTs. Key advantages include high-speed response, high common-mode rejection, and a wide operating voltage and temperature range.
