Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the HCPL-314J has a very low
maximum V
the lead inductance from the HCPL-314J to the IGBT gate
and emitter (possibly by mounting the HCPL-314J 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 19. Care should be taken with
such a PC board design to avoid routing the IGBT collec-
tor or emitter traces close to the HCPL-314J input as this
can result in unwanted coupling of transient signals into

the input of HCPL-314J and degrade performance. (If the
IGBT drain must be routed near the HCPL-314J 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-314J.) An external
clamp diode may be connected between pins 14 & 15
and pins 9 & 10 (as shown in Figure 19) for the protec-
tion of HCPL-314J in the case of IGBTs switching induc-
tive load.
