Photocouplers. DESCRIPTION The LTV-5 optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications and inverters in power supply system. It contains an AlGaAs LED optically coupled to an integrated circuit with a power output stage. The.A peak output current is capable of directly driving most IGBTs with ratings up to V/5 A. For IGBTs with higher ratings, the 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 -4 o C ~ +5 o C.. Features Functional Diagram.

(As page 6) Notes: ) Maximum pulse width = μs, maximum duty cycle =.%. ) Output is sourced at -.8 A with a maximum pulse width = μs. V CC-V O is measured to ensure 5 V or below. ) Output is sourced at.8a with a maximum pulse width = μs. V O-V EE is measured to ensure 5 V or below. 4) In this test V OH is measured with a load current. When driving capacitive loads, V OH will approach V CC as I OH approaches zero amps. 5) Device is considered a two terminal device: pins,, and 4 are shorted together and pins 5, 6, 7 and 8 are shorted together. 6) According to UL577, each photocoupler is tested by applying an insulation test voltage 55 V RMS for one second (leakage current less than μa). This test is performed before the % production test for partial discharge 7) The difference between T PHL and T PLH between any two LTV-5 parts under same test conditions. 8) Common mode transient immunity in high stage is the maximum tolerable negative dv CM/dt on the trailing edge of the common mode impulse signal, V CM, to assure that the output will remain high. 9) Common mode transient immunity in low stage is the maximum tolerable positive dv CM/dt on the leading edge of the common mode impulse signal, V CM, to assure that the output will remain low. ) Pulse Width Distortion is defined as T PHL - T PLH for any given device. ) At least a.μf or bigger bypass capacitor must be connected/ closed across pin 8 and pin 5. Failure to provide the bypass may impair the switching property. Normally, it is recommended to place a μf multi-layer ceramic capacitor. To parallel one larger capacitor (>μf) to optimize performance is better. 9/6 Part No. :
