L I T E - O N T E C H N O L O G Y C O RP O R AT I O N Property of Lite-on Only LTV-3120 2.5A Output Current, High CMR, Gate Drive Optocoupler Apr 2011 Description Features The LTV-3120 optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications and inverters in power supply system. It contains a AlGaAs LED optically coupled to an integrated circuit with a power output stage. The 2.5A peak output current is capable of directly driving most IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the LTV-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The Optocoupler operational parameters are guaranteed over the temperature range from -40oC ~ +100oC. 1 8 Vcc Anode 2 7 Vo Cathode 3 6 Vo NC 4 5 GND 2.5 A maximum peak output current • 25 kV/us minimum Common Mode Rejection (CMR) at VCM = 1500 V • 3.8 mA maximum supply current (ICC) • Under Voltage Lock-Out protection (UVLO) with hysteresis • Wide operating range: 15 to 30 Volts (VCC) • Guaranteed performance over temperature -40oC ~ +100oC. • Offer low power dissipation with RON ≤ 1Ω • Fast switching speed, 500ns max propagation delay • Safety approval: UL, cUL, VDE (In process) Application Functional Diagram NC • • IGBT/MOSFET gate drive • Uninterruptible power supply (UPS) • Industrial Inverter • Induction heating Truth Table LED VCC-GND (Turn-ON, +ve going) VCC-GND (Turn-OFF, -ve going) VO OFF ON ON ON 0 - 30 V 0 – 11.5 V 11.5 - 13.5 V 13.5 - 30 V 0 - 30 V 0 – 10 V 10 - 12 V 12 - 30 V Low Low Transition High Shield A 0.1µF bypass Capacitor must be connected between Pin 5 and 8.
