LITE-ON TECHNOLOGY CORPORATION Property of Lite-on Only LTV-3150 0.6A Output Current, High CMR, Apr 2011 Gate Drive Optocoupler Description Features The LTV-3150 optocoupler is ideally suited 0.6A maximum peak output current for driving power IGBTs and MOSFETs used in motor control inverter applications 15 kV/us minimum Common Mode Rejection (CMR) at VCM = 1500 V and inverters in power supply system. It contains an AlGaAs LED optically coupled to 3.5 mA maximum supply current (I ) CC an integrated circuit with a power output Under Voltage Lock-Out protection (UVLO) with stage. The 0.6A peak output current is hysteresis capable of directly driving most IGBTs with Wide operating range: 15 to 30 Volts (V ) CC ratings up to 1200 V/50 A. For IGBTs with Guaranteed performance over temperature o o higher ratings, the LTV-3150 series can be -40 C ~ +100 C. used to drive a discrete power stage which Fast switching speed, 500ns max propagation drives the IGBT gate. delay Safety approval: Pending The Optocoupler operational parameters are guaranteed over the temperature range o o from -40 C ~ +100 C.
