Data Sheet HCPL- (Single Channel), HCPL-J (Dual Channel). Amp Output Current IGBT Gate Drive Optocoupler Overview The HCPL-X consists of an LED optically coupled to an integrated circuit with a power output stage. This optocoupler is 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 this optocoupler makes it ideally suited for directly driving IGBTs with ratings up to V/A. For IGBTs with higher ratings, the HCPL-/J can be used to drive a discrete power stage which drives the IGBT gate.

The HCPL-/J realizes this very low V OL by using a DMOS transistor with Ω (typical) on resistance in its pull-down circuit. When the HCPL/J is in the low state, the IGBT gate is shorted to the emitter by Rg + Ω. Minimizing Rg and the lead inductance from the HCPL-/J to the IGBT gate and emitter (possibly by mounting the HCPL-/J 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 and Figure. Care should be taken with such a PC board design to avoid routing the IGBT collector or emitter traces close to the HCPL-/J input as this can result in unwanted coupling of transient signals into the HCPL-/ J and degrade performance. (If the IGBT drain must be routed near the HCPL-/J 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- /J.)

Amp Output Current IGBT Gate Drive Optocoupler Selecting the Gate Resistor (Rg) to Minimize IGBT Switching Losses Step : Calculate Rg Minimum From the IOL Peak Specification.

Ω The V OL value of V in the previous equation is a conservative value of V OL at the peak current of.a (see Figure ). At lower Rg values the voltage supplied by the HCPL-/J 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 V EE in the previous equation is equal to zero volts. Step : Check the HCPL-/J Power Dissipation and Increase Rg if Necessary.

Amp Output Current IGBT Gate Drive Optocoupler Thermal Model (HCPL-) The steady state thermal model for the HCPL- is shown in Figure 9. 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 θ CA which raises the case temperature T C accordingly. The value of θ CA depends on the conditions of the board design and is, therefore, determined by the designer. The value of θ CA = C/W was obtained from thermal measurements using a. in.. in. PC board, with small traces (no ground plane), a single HCPL- soldered into the center of the board and still air. The absolute maximum power dissipation derating specifications assume a θ CA value of C/W. For Qg = nc, from Table, a value of E SW =. µj gives a Rg = Ω.

HCPL- (Single Channel), HCPL-J (Dual Channel) Data Sheet LED Drive Circuit Considerations for Ultra High CMR Performance 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. The HCPL-/J 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 to as shown in Figure. 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 and Figure ), can achieve kv/µs 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 (CMR H ) 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 ma provides adequate margin over the maximum I FLH of ma to achieve kv/µs CMR. Figure : Energy Dissipated in the HCPL- for Each IGBT Switching Cycle.. Amp Output Current IGBT Gate Drive Optocoupler CMR with the LED Off (CMR L ) A high CMR LED drive circuit must keep the LED off (V F V F(OFF) ) during common mode transients. For example, during a dv CM /dt transient in Figure, the current flowing through C LEDP also flows through the R SAT and V SAT of the logic gate. As long as the low state voltage developed across the logic gate is less than V F(OFF), the LED will remain off and no common mode failure will occur. The open collector drive circuit, shown in Figure, cannot keep the LED off during a +dv CM /dt transient, since all the current flowing through C LEDN must be supplied by the LED, and it is not recommended for applications requiring ultra-high CMR L performance. Figure is an alternative drive circuit which, like the recommended application circuit (Figure and Figure ), does achieve ultra-high CMR performance by shunting the LED in the off state. Under Voltage Lockout Feature The HCPL-/J contains an under voltage lockout (UVLO) feature that is designed to protect the IGBT under fault conditions that cause the HCPL-/J 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-/J output is in the high state and the supply voltage drops below the HCPL-/J V UVLO- threshold (9. < V UVLO- <.), the optocoupler output will go into the low state with a typical delay, UVLO Turn Off Delay, of. µs. When the HCPL-/J output is in the low state and the supply voltage rises above the HCPL-/J V UVLO+ threshold (. < V UVLO+ <.), the optocoupler will go into the high state (assuming LED is ON ) with a typical delay, UVLO TURN On Delay, of. µs.

HCPL- (Single Channel), HCPL-J (Dual Channel) Data Sheet. Amp Output Current IGBT Gate Drive Optocoupler IPM Dead Time and Propagation Delay Specifications The HCPL-/J 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 (Q and Q in Figure ) are off. Any overlap in Q and Q conduction will result in large currents flowing through the power devices from the high- to the lowvoltage motor rails. To minimize dead time in a given design, the turn on of LED should be delayed (relative to the turn off of LED) so that under worst-case conditions, transistor Q has just turned off when transistor Q turns on, as shown in Figure. The amount of delay necessary to achieve this condition is equal to the maximum value of the propagation delay difference specification, PDD MAX, which is specified to be ns over the operating temperature range of C to C. 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 9. The maximum dead time for the HCPL-/J is ns (= ns ( ns)) over an operating temperature range of C to C. 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.
