Applications Information Eliminating Negative IGBT
Gate Drive
To keep the IGBT firmly off, the HCPL-3020 and HCPL-
0302 have a very low maximum V
1.0 V. Minimizing R
HCPL-3020 or HCPL-0302 to the IGBT gate and emitter
(possibly by mounting the HCPL-3020 or HCPL-0302 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 emit-
ter traces close to the HCPL-3020 or HCPL-0302 input as
this can result in unwanted coupling of transient signals
into the input of HCPL-3020 or HCPL-0302 and degrade
performance. (If the IGBT drain must be routed near the
HCPL-3020 or HCPL-0302 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-3020 or HCPL-0302.
