Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the HCPL-J314 has a very low
maximum V
the lead inductance from the HCPL-J314 to the IGBT gate
and emitter (possibly by mounting the HCPL-J314 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 19. Care should be taken with such a
PC board design to avoid routing the IGBT collector or

emitter traces close to the HCPL-J314 input as this can
result in unwanted coupling of transient signals into the
input of HCPL-J314 and degrade performance. (If the
IGBT drain must be routed near the HCPL-J314 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-J314.)
