Applications Information
Eliminating Negative IGBT
Gate Drive
To keep the IGBT firmly off, the
HCPL-3150/315J has a very low
maximum V
OL
specification of
1.0 V. The HCPL-3150/315J
realizes this very low V
OL
by using
a DMOS transistor with 4
(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
.
Minimizing 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 degrade 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 transient signals coupled
from the IGBT drain from turning
on the HCPL-3150/315J.)
