Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the HCPL-3150/315J has a
very low maximum V specification of 1.0V. The HCPL-
OL
3150/315J realizes this very low V by using a DMOS
OL
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 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-
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.)
