ENABLE
ENBL provides an alternate means of controlling the out-
put. If ENBL is used as the primary input, B must be con-
nected to V
CC
and A to V
EE
. ENBL can be driven by the
output of an optoisolator from ENBL to COM as shown in
Figure 7. If ENBL is not used, it should be connected to
COM.
Figure 7.
Using ENBL as Primary Input
EXTERNAL BIPOLAR SUPPLIES
If it is desired to drive an emitter grounded IGBT from ex-
ternal supplies, the configuration in Figure 8 should be
used. COM should never be connected to ground. V
CC
must be
≥
12V and V
CC
-V
EE
must be
≥
23.5V.
