The HCPL-3150/315J OL realizes this very low V by using a DMOS transistor with 4Ω (typical) on resistance in its pull-down circuit. When the OL HCPL3150/315J is in the low state, the IGBT gate is shorted to the emitter by Rg + 4Ω. 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 in many applications as shown in Figure25 and Figure26. Care should be taken with such a PC board design to avoid routing the IGBT collector or emitter traces close to the HCPL-3150/315J 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.)
