Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the HCPL-3150/315J has a
very low maximum V
3150/315J realizes this very low V
transistor with 4 Ω (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 Ω. Minimiz-
ing 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 applica tions 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-
3150/315J input as this can result in unwanted coupling
of transient signals into the HCPL-3150/315J and de-
grade 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 tran-
sient signals coupled from the IGBT drain from turning
on the HCPL-3150/315J.)
