Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the ACPL-P302/W302 has a
very low maximum V
R
to the IGBT gate and emitter (possibly by mounting the
ACPL-P302/W302 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 17. Care should
be taken with such a PC board design to avoid routing
the IGBT collector or emitter traces close to the ACPL-
P302/W302 input as this can result in unwanted coupling
of transient signals into the input of ACPL-P302/W302 and
degrade performance. (If the IGBT drain must be routed
near the ACPL-P302/W302 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 ACPL-P302/W302.
