Applications Information Eliminating Negative IGBT
Gate Drive
To keep the IGBT firmly off, the HCPL-3020 and HCPL-
0302 have a very low maximum VOL specification of
1.0 V. Minimizing Rg and the lead inductance from the
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.

Description
The HCPL-3020 and HCPL-0302 consist of a GaAsP LED optically coupled to an integrated circuit with a power output stage. These optocouplers are ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate-controlled devices. The voltage and current supplied by this optocoupler makes it ideally suited for directly driving small or medium power IGBTs. For IGBTs with higher ratings, the HCPL-0314/3140 (0.6 A), HCPL-3150 (0.6 A) or HCPL-3120 (2.5 A) gate drive opto-couplers can be used.
