LTV-3120 Lite-On

LITE-ON TECHNOLOGY CORPORATION Property of Lite-on Only LTV-3120 2.5 Amp Output Current IGBT Gate Driver Optocoupler with Rail-to-Rail Output Voltage Description Features 2.5 A maximum peak output current The LTV-3120 optocoupler is ideally suited for driving power IGBTs and MOSFETs 2.0A minimum peak output current used in motor control inverter applications Rail-to-rail output voltage and inverters in power supply system. It 400 ns maximum propagation delay contains a AlGaAs LED optically coupled to 250 ns maximum propagation delay difference an integrated circuit with a power output Under Voltage Lock-Out protection (UVLO) with stage. The 2.5A peak output current is hysteresis capable of directly driving most IGBTs with 25 kV/us minimum Common Mode Rejection ratings up to 1200 V/100 A. For IGBTs with (CMR) at VCM = 1500 V higher ratings, the LTV-3120 series can be I = 3.0 mA maximum supply current CC used to drive a discrete power stage which drives the IGBT gate. Wide operating range: 15 to 30 Volts (V ) CC The Optocoupler operational parameters Guaranteed performance over temperature o o are guaranteed over the temperature range -40 C ~ +100 C. o o from -40 C ~ +100 C.
