It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to a CMOS integrated circuit with a power stage. The power stage consists of a PMOS pullup and a NMOS pull-down power transistor. It is ideally suited for high frequency driving of MOSFETs used in Plasma Display Panels (PDPs), motor control invertor applications, and high performance DC/DC converters. The device is packaged in an 8-pin dual in-line housing compatible with 260°C reflow processes for lead free solder compliance. +85°C 0.5A minimum peak output current High speed response: 500ns max propagation delay over temperature range Wide VCC operating range: 10V to 20V 5000Vrms, 1 minute isolation Minimum creepage distance of 7.0mm Minimum clearance distance of 7.0mm C-UL, UL and VDE* approved 10kV/µs minimum common mode rejection (CMR) at VCM = 1,500V RDS(ON) of 1.5Ω (typ.) offers lower power dissipation Applications ■ Plasma Display Panel ■ High performance DC/DC convertor ■ High performance switch mode power supply ■ High performance uninterruptible power supply ■ Isolated Power MOSFET gate drive *Requires ‘V’ ordering option Functional Block Diagram FOD3181 NO CONNECTION 1 8 VCC ANODE 2 7 OUTPUT 8 1 CATHODE 3 6 OUTPUT NO CONNECTION 4 5 VEE 8 Note: A 0.1µF bypass capacitor must be connected between pins 5 and 8. 8 1 1 ©2006 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FOD3181 Rev. 1.0.3 FOD3181 0.5A Ouput Current, High Speed MOSFET Gate Driver Optocoupler Absolute Maximum Ratings Symbol TSTG TOPR TJ TSOL IF(AVG) IF(tr) IF(TRAN) VR IOH(PEAK) IOL(PEAK) VCC – VEE VO(PEAK) PO PD Parameter Storage Temperature Operating Temperature Junction Temperature Lead Solder Temperature Average Input Current(1) Minimum Rate of Rise of LED Current Peak Transient Input Current ( 5V Min. 0.5 0.5 VCC – 0.5 Typ.* Max.

Derate linearly above +70°C free air temperature at a rate of 0.3mA/°C. 2. The output currents IOH and IOL are specified with a capacitive current limited load = (3 x 0.01µF) + 0.5Ω, frequency = 8kHz, 50% DF. The maximum pulse width of the output current is 300ns, maximum duty cycle = 0.48%. Output currents specified for different values of VDS for VCC – VEE = 20V with the formula: VOH = (VCC – VEE) – (IOH x RDS(ON)). This guarantees operation at IO peak minimum = 2.0A for -40°C to +100°C operating temperature range. 3. The output currents IOH and IOL are specified with a capacitive current limited load = (3 x 0.01µF) + 40Ω, frequency = 8kHz, 50% DF. The maximum pulse width of the output current is 1.5µs, maximum duty cycle = 2.4%. Output currents specified for different values of VDS for VCC – VEE = 20V with the formula: VOL = (VCC – VEE) – (IOL x RDS(ON)). This guarantees operation at IO peak minimum = 0.5A for -40°C to +100°C operating temperature range. 4. 5. 6. 7. No derating required across operating temperature range. In this test, VOH is measured with a dc load current. When driving capacitive load VOH will approach VCC as IOH approaches zero amps. Maximum pulse width = 1ms, maximum duty cycle = 20%. tPHL propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the falling edge of the VO signal. tPLH propagation delay is measured from the 50% level on the rising edge of the input pulse to the 50% level of the rising edge of the VO signal. Pin 1 and 4 need to be connected to LED common. Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse VCM to assure that the output will remain in the high state (i.e. VO > 10.0V). 8. 9. 10. Common mode transient immunity in a low state is the maximum tolerable dVCM/dt of the common mode pulse, VCM, to assure that the output will remain in a low state (i.e. VO < 1.0V). 11. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000Vrms for 1 second (leakage detection current limit II-O < 5µA). 12. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted together. 4 FOD3181 Rev. 1.0.3 www.fairchildsemi.com FOD3181 0.5A Ouput Current, High Speed MOSFET Gate Driver Optocoupler Typical Performance Curves Fig. 1 Input Forward Current vs. Forward Voltage I FLH – Low To High Input Current Threshold (mA) 100 6 V 5 CC Fig. 2 Low To High Input Current Threshold vs. Ambient Temperature = 10 to 20V VEE = 0 Output = Open 10 I F – Forward Current (mA) 1 TA = 100oC TA = -40oC 4 3 0.1 TA = 25oC 2 0.01 1 0.001 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 2.2 0 -40 -20 0 20 40 60 80 100 VF – Forward Voltage (V) TA – Ambient Temperature (°C) Fig. 3 Output Low Voltage vs. Ambient Temperature 0.30 VF(OFF) = -3.0 to 0.8V IOUT = 100mA V = 10 to 20V CC Fig. 4 High Output Voltage Drop vs. Ambient Temperature 0.00 (VOH - VCC) – High Output Voltage Drop (V) V -0.05 CC = 10 to 20V, VEE = 0 0.25 V OL – Output Low Voltage (V) IF = 10 to 16 mA IOUT = -100 mA VEE = 0 0.20 -0.10 0.15 -0.15 0.10 -0.20 0.05 -0.25 0.00 -40 -20 0 20 40 60 80 100 -0.30 -40 -20 0 20 40 60 o 80 100 TA – Ambient Temperature (°C) TA – Ambient Temperature ( C) Fig. 5 Supply Current vs. Ambient Temperature 6.2 V 5.8 CC Fig. 6 Supply Current vs. Supply Voltage 6.2 IF = 10mA (for ICCH) IF = 0mA (for ICCL) TA = 25oC, VEE = 0V = 20V, VEE = 0 IF = 10 mA (for ICCH) IF = 0 mA (for ICCL) 5.8 I CC – Supply Current (mA) 5.4 ICCL 5.0 ICCH 4.6 I CC – Supply Current (mA) 5.4 5.0 ICCL 4.6 ICCH 4.2 4.2 3.8 -40 -20 0 20 40 60 80 100 3.8 10 12 14 16 18 20 TA – Ambient Temperature (°C) VCC – Supply Voltage (V) 5 FOD3181 Rev. 1.0.3 www.fairchildsemi.com FOD3181 0.5A Ouput Current, High Speed MOSFET Gate Driver Optocoupler Fig. 7 Propagation Delay vs. Load Capacitance 200 VCC = 20V, VEE = 0 180 IF = 10mA, TA = 25 C o Fig. 8 Propagation Delay vs. Forward LED Current 200 VCC = 20V, VEE = 0 180 RG = 10Ω, CG = 10nF f = 250 kHz, D.
