Applications Information
Eliminating Negative IGBT Gate Drive (Discussion applies 
to HCPL-3120, HCPL-J312, and HCNW3120)
To  keep  the  IGBT  firmly  off,  the  HCPL-3120  has  a  very 
low maximum V
realizes  this  very  low  V
with  1 Ω  (typical)  on  resistance  in  its  pull  down  circuit. 
When  the  HCPL-3120  is  in  the  low  state,  the  IGBT  gate 
is  shorted  to  the  emitter  by  Rg  +  1 Ω.  Minimizing  Rg 
and  the  lead  inductance  from  the  HCPL-3120  to  the 
IGBT gate and emitter (possibly by mounting the HCPL-

3120 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-3120 input 
as  this  can  result  in  unwanted  coupling  of  transient 
signals into the HCPL-3120 and degrade performance. (If 
the IGBT drain must be routed near the HCPL-3120 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-3120.)
