The LED is optically coupled to an integrated circuit with a power output stage. These optocouplers are ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The HCNW3120 has the highest insulation voltage of VIORM = 1414 Vpeak in the VDE0884. The HCPL-J312 has an insulation voltage of VIORM = 891 Vpeak and the VIORM = 630 Vpeak is also available with the HCPL-3120 (Option 060).

DIN IEC 112/VDE 0303 Part 1 Material Group (DIN VDE 0110, 1/89, Table 1) 7 All Agilent data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. For creepage, the shortest distance path along the surface of a printed circuit board between the solder fillets of the input and output leads must be considered. There are recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and clearances. Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level.

The HCPL-3120 realizes this very low VOL by using a DMOS transistor with 1 (typical) on resistance in its pull down circuit. When the HCPL- 3120 is in the low state, the IGBT gate is shorted to the emitter by Rg + 1 . Minimizing Rg and the lead inductance from the HCPL3120 to the IGBT gate and emitter (possibly by mounting the HCPL-3120 on a small PC board directly above the IGBT) can eliminate the need for negative IGBT gate drive in many applications as shown in Figure 25. Care should be taken with such a PC board design to avoid routing the IGBT collector or emitter traces close to the HCPL-3120 input as this can result in unwanted coupling of transient signals into the HCPL-3120 and degrade performance. (If the IGBT drain must be routed near the HCPL3120 input, then the LED should be reverse-biased when in the off state, to prevent the transient signals coupled from the IGBT drain from turning on the HCPL-3120.)

(Discussion applies to HCPL-3120, HCPLJ312 and HCNW3120) Step 1: Calculate Rg Minimum from the IOL Peak Specification. The IGBT and Rg in Figure 26 can be analyzed as a simple RC circuit with a voltage supplied by the HCPL-3120. (VCC - VEE - VOL) Rg --------------- I OLPEAK (VCC - VEE - 2 V) = --------------- I OLPEAK (15 V + 5 V - 2 V) = ------------------ 2.5 A = 7.2 8 The VOL value of 2 V in the previous equation is a conservative value of VOL at the peak current of 2.5A (see Figure 6). At lower Rg values the voltage supplied by the HCPL-3120 is not an ideal voltage step. This results in lower peak currents (more margin) than predicted by this analysis. When negative gate drive is not used VEE in the previous equation is equal to zero volts.

HCPL-3120 Typical Application Circuit with Negative IGBT Gate Drive. - HVDC 19 Step 2: Check the HCPL-3120 Power Dissipation and Increase Rg if Necessary. The HCPL-3120 total power dissipation (PT) is equal to the sum of the emitter power (PE ) and the output power (PO): P T = PE + PO PE = IF * VF * Duty Cycle PO = PO(BIAS) + PO (SWITCHING) = ICC* (VCC - VEE) + ESW(R G, QG) * f For the circuit in Figure 26 with IF (worst case) = 16 mA, Rg = 8 , Max Duty Cycle = 80%, Qg = 500 nC, f = 20 kHz and TA max = 85C: The value of 4.25 mA for ICC in the previous equation was obtained by derating the ICC max of 5 mA (which occurs at -40C) to ICC max at 85C (see Figure 7). Since PO for this case is greater than PO(MAX), Rg must be increased to reduce the HCPL-3120 power dissipation. PO(SWITCHING MAX) = PO(MAX) - PO(BIAS) = 178 mW - 85 mW = 93 mW PO(SWITCHINGMAX) ESW(MAX) = --------------- f PE = 16 mA * 1.8 V * 0.8 = 23 mW PO = 4.25 mA * 20 V + 5.2 J* 20 kHz = 85 mW + 104 mW = 189 mW > 178 mW (PO(MAX) @ 85C = 250 mW-15C*4.8 mW/C) PE Parameter IF VF Duty Cycle Description LED Current LED On Voltage Maximum LED Duty Cycle 93 mW = ------- = 4.65 W 20 kHz For Qg = 500 nC, from Figure 27, a value of E SW = 4.65 W gives a Rg = 10.3 .

The thermal resistance values given in this model can be used to calculate the temperatures at each node for a given operating condition. As shown by the model, all heat generated flows through CA which raises the case temperature TC accordingly. The value of CA depends on the conditions of the board design and is, therefore, determined by the designer. The value of CA = 83C/W was obtained from thermal measurements using a 2.5 x 2.5 inch PC board, with small traces (no ground plane), a single HCPL3120 soldered into the center of the board and still air. The absolute maximum power dissipation derating specifications assume a CAvalue of 83C/W. Inserting the values for LC and DC shown in Figure 28 gives: From the thermal mode in Figure 28 the LED and detector IC junction temperatures can be expressed as: For example, given PE = 45 mW, PO = 250 mW, TA = 70C and CA = 83C/W: TJE = PE * (LC||(LD + DC) + CA) LC * DC + PD * ---------------- + CA + TA LC + DC + LD ( TJD = PE ) LC * DC --------------- + CA LC + DC + LD ( ) + PD* (DC||(LD + LC) + CA) + TA TJE = PE * (256C/W + CA) + PD* (57C/W + CA) + TA TJD = PE * (57C/W + CA) + PD* (111C/W + CA) + TA TJE = PE* 339C/W + PD* 140C/W + TA = 45 mW* 339C/W + 250 mW * 140C/W + 70C = 120C TJD = PE* 140C/W + PD* 194C/W + TA = 45 mW* 140C/W + 250 mW * 194C/W + 70C = 125C TJE and TJD should be limited to 125C based on the board layout and part placement (CA) specific to the application.

(Discussion applies to HCPL3120, HCPL-J312, and HCNW3120) Without a detector shield, the dominant cause of optocoupler CMR failure is capacitive coupling from the input side of the optocoupler, through the package, to the detector IC as shown in Figure 29. The HCPL3120 improves CMR performance 1 by using a detector IC with an optically transparent Faraday shield, which diverts the capacitively coupled current away from the sensitive IC circuitry. However, this shield does not eliminate the capacitive coupling between the LED and optocoupler pins 5-8 as shown in Figure 30. This capacitive coupling causes perturbations in the LED current during common mode transients and becomes the major source of CMR failures for 8 1 7 2 CLEDP 2 CLEDO1 a shielded optocoupler. The main design objective of a high CMR LED drive circuit becomes keeping the LED in the proper state (on or off) during common mode transients. For example, the recommended application circuit (Figure 25), can achieve 15 kV/s CMR while minimizing component complexity. Techniques to keep the LED in the proper state are discussed in the next two sections. 8 CLEDP 7 CLEDO2 3 4 CLEDN 6 3 5 4 Figure 29.

Optocoupler Input to Output Capacitance Model for Shielded Optocouplers. 22 CMR with the LED On (CMRH). CMR with the LED Off (CMRL). A high CMR LED drive circuit must keep the LED on during common mode transients. This is achieved by overdriving the LED current beyond the input threshold so that it is not pulled below the threshold during a transient. A minimum LED current of 10 mA provides adequate margin over the maximum IFLH of 5 mA to achieve 15 kV/s CMR. A high CMR LED drive circuit must keep the LED off (VF VF(OFF)) during common mode transients. For example, during a -dVcm/dt transient in Figure 31, the current flowing through CLEDP also flows through the RSAT and VSAT of the logic gate. As long as the low state voltage developed across the logic gate is less than VF(OFF), the LED will remain off and no common mode failure will occur. +5 V 1 8 0.1 F CLEDP 2 + VSAT - The open collector drive circuit, shown in Figure 32, cannot keep the LED off during a +dVcm/dt transient, since all the current flowing through CLEDN must be supplied by the LED, and it is not recommended for applications requiring ultra high CMRL performance. Figure 33 is an alternative drive circuit which, like the recommended application circuit (Figure 25), does achieve ultra high CMR performance by shunting the LED in the off state. 7 + - VCC = 18 V 1 ILEDP 3 CLEDP *** 6 CLEDN 4 8 +5 V 2 Rg 5 SHIELD *** 3 Q1 7 CLEDN 6 ILEDN * THE ARROWS INDICATE THE DIRECTION OF CURRENT FLOW DURING -dVCM/dt. 4 SHIELD + - VCM Figure 31.

(Discussion applies to HCPL-3120, HCPL-J312, and HCNW3120) The HCPL-3120 contains an under voltage lockout (UVLO) feature that is designed to protect the IGBT under fault conditions which cause the HCPL-3120 supply voltage (equivalent to the VO - OUTPUT VOLTAGE - V 14 12 (12.3, 10.8) 10 (10.7, 9.2) 8 6 4 2 0 (10.7, 0.1) 0 5 10 (12.3, 0.1) 15 20 (VCC - VEE ) - SUPPLY VOLTAGE - V Figure 34. Under Voltage Lock Out. fully-charged IGBT gate voltage) to drop below a level necessary to keep the IGBT in a low resistance state. When the HCPL-3120 output is in the high state and the supply voltage drops below the HCPL-3120 VUVLO- threshold (9.5 < VUVLO- < 12.0) the optocoupler output will go into the low state with a typical delay, UVLO Turn Off Delay, of 0.6 s. When the HCPL-3120 output is in the low state and the supply voltage rises above the HCPL3120 VUVLO+ threshold (11.0 < VUVLO+ < 13.5) the optocoupler output will go into the high state (assumes LED is "ON") with a typical delay, UVLO Turn On Delay of 0.8 s. IPM Dead Time and Propagation Delay Specifications. (Discussion applies to HCPL-3120, HCPLJ312, and HCNW3120) The HCPL-3120 includes a Propagation Delay Difference (PDD) specification intended to help designers minimize "dead time" in their power inverter designs. Dead time is the time period during which both the high and low side power transistors (Q1 and Q2 in Figure 25) are off. Any overlap in Q1 and Q2 conduction will result in large currents flowing through the power devices between the high and low voltage motor rails.

Thermal Derating Curve, Dependence of Safety Limiting Value with Case Temperature per VDE 0884. To minimize dead time in a given design, the turn on of LED2 should be delayed (relative to the turn off of LED1) so that under worst-case conditions, transistor Q1 has just turned off when transistor Q2 turns on, as shown in Figure 35. The amount of delay necessary to achieve this conditions is equal to the maximum value of the propagation delay difference specification, PDDMAX, which is specified to be 350 ns over the operating temperature range of -40C to 100C. Delaying the LED signal by the maximum propagation delay difference ensures that the minimum dead time is zero, but it does not tell a designer what the maximum dead time will be. The maximum dead time is equivalent to the difference between the maximum and minimum propagation delay difference specifications as shown in Figure 36. The maximum dead time for the HCPL-3120 is 700 ns (= 350 ns (-350 ns)) over an operating temperature range of -40C to 100C. Note that the propagation delays used to calculate PDD and dead time are taken at equal temperatures and test conditions since the optocouplers under consideration are typically mounted in close proximity to each other and are switching identical IGBTs. www.agilent.com/semiconductors For product information and a complete list of distributors, please go to our web site.
