Derate linearly above 70C free-air temperature at a rate of 0.3 mA/C. 2. Maximum pulse width = 10 s, maximum duty cycle = 0.2%. This value is intended to allow for component tolerances for designs with IO peak minimum = 0.5 A. See Applications section for additional details on limiting IOH peak. 3. Derate linearly above 70C free-air temperature at a rate of 4.8 mW/C. 4. Derate linearly above 70C free-air temperature at a rate of 5.4 mW/C. The maximum LED junction temperature should not exceed 125C. 5. Maximum pulse width = 50 s, maximum duty cycle = 0.5%. 6. In this test VOH is measured with a dc load current. When driving capacitive loads VOH will approach VCC as IOH approaches zero amps. 7. Maximum pulse width = 1 ms, maximum duty cycle = 20%. 8. In accordance with UL1577, each HCPL-3150 optocoupler is proof tested by applying an insulation test voltage 4500 Vrms ( 6000 Vrms for the HCPL-315J) for 1 second. This test is performed before the 100% production test for partial discharge (method b) shown in the IEC/EN/ DIN EN 60747-5-2 Insulation Characteristics Table, if applicable. 9. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted together. 10. The difference between tPHL and tPLH between any two parts or channels under the same test condition. 11. Pins 1 and 4 (HCPL-3150) and pins 3 and 4 (HCPL-315J) need to be connected to LED common. 12. 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 > 15.0 V). 13. 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 < 1.0 V). 14. This load condition approximates the gate load of a 1200 V/25 A IGBT. 15. Pulse Width Distortion (PWD) is defined as |tPHL-tPLH| for any given device. 16. Each channel. 17. Device considered a two terminal device: Channel one output side pins shorted together, and channel two output side pins shorted together. 18.

Applications Information Eliminating 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 HCPL3150/315J input as this can result in unwanted coupling of transient signals into the HCPL-3150/315J and degrade performance. (If the IGBT drain must be routed near the HCPL-3150/315J 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-3150/315J.) To keep the IGBT firmly off, the HCPL-3150/315J has a very low maximum VOL specification of 1.0 V. The HCPL3150/315J realizes this very low VOL by using a DMOS transistor with 4 (typical) on resistance in its pull down circuit. When the HCPL-3150/315J is in the low state, the IGBT gate is shorted to the emitter by Rg + 4 . Minimizing Rg and the lead inductance from the HCPL-3150/315J to the IGBT gate and emitter (possibly by mounting the HCPL-3150/315J on a small PC board directly above the IGBT) can eliminate the need for negative IGBT gate drive HCPL-3150 +5 V 1 270 8 0.1 F 2 + - VCC = 18 V + HVDC 7 Rg CONTROL INPUT 74XXX OPEN COLLECTOR 3 6 4 5 Figure 25a.

At lower Rg values the voltage supplied by the HCPL-3150/315J is not an ideal voltage step. This results in lower peak currents (more margin) than predicted by this analysis.

Since PO for this case is greater than PO(MAX), Rg must be increased to reduce the HCPL-3150 power dissipation.

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 TCA which raises the case temperature TC accordingly. The value of TCA depends on the conditions of the board design and is, therefore, determined by the designer. The value of TCA = 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 HCPL-3150 soldered into the center of the board and still air.

The HCPL-3150/315J improves CMR performance by using a detector IC with an optically transparent Faraday shield, which diverts the capacitively coupled current away from the sensitive IC circuitry. How ever, 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 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. CMR with the LED On (CMRH) Esw - ENERGY PER SWITCHING CYCLE - J 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. 7 Qg = 100 nC Qg = 250 nC Qg = 500 nC 6 5 VCC = 19 V VEE = -9 V 4 3 2 1 0 0 20 40 60 80 100 Rg - GATE RESISTANCE - Figure 27. Energy Dissipated in the HCPL-3150 for Each IGBT Switching Cycle. 18 CMR with the LED Off (CMRL) 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. 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. Under Voltage Lockout Feature The HCPL-3150/315J contains an under voltage lockout (UVLO) feature that is designed to protect the IGBT under fault conditions which cause the HCPL-3150/315J supply voltage (equivalent to the fully-charged IGBT gate voltage) to drop below a level necessary to keep the IGBT in a low resistance state. When the HCPL-3150/315J output is in the high state and the supply voltage drops below the HCPL-3150/315J 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-3150/315J output is in the low state and the supply voltage rises above the HCPL-3150/315J VUVLO+ threshold (11.0 < VUVLO+ < 13.5), the optocoupler will go into the high state (assuming LED is "ON") with a typical delay, UVLO TURN On Delay, of 0.8 s. IPM Dead Time and Propagation Delay Specifications The HCPL-3150/315J 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 from the high- to the low-voltage motor rails. 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 34. 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. 1 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 35. The maximum dead time for the HCPL-3150/315J 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. 8 1 2 7 2 3 6 3 5 4 CLEDO1 CLEDP 8 CLEDP 7 CLEDO2 CLEDN 4 Figure 29.
