2.5A Output Current, High CMR, IGBT Gate Drive Optocoupler


The LTV-3120 series contains a GaAsP LED optically coupled to an integrated circuit with a power output stage. The ideally suited for driving power IGBTs and MOSFETs used in motor control, inverter and industrial applications.
The 2.5A peak output current driving is capable of directly driving most IGBTs with ratings up to 1,200V / 100A. For IGBTs with higher ratings, the LTV-3120 series can be used to drive a discrete power stage which drives the IGBT gate.
The LTV-3120 have an operating temperature of -40 oC - 100 oC, this makes ideal for use in applications that operate in industrial environments.
