Higher Output Current Using an External Current Buf-
fer:
To increase the IGBT gate drive current, a non-inverting
current buffer (such as the npn/pnp buffer shown in
Figure 75) may be used. Inverting types are not com-
patible with the desatura-tion fault protection circuitry
and should be avoided. To preserve the slow IGBT turn-
off feature during a fault condition, a 10 nF capacitor
should be connected from the buffer input to V
a 10 : resistor inserted between the output and the
common npn/pnp base. The MJD44H11/MJD45H11
pair is appropriate for currents up to 8A maximum. The
D44VH10/ D45VH10 pair is appropriate for currents up
to 15 A maximum.

DESAT Diode and DESAT Threshold
The DESAT diode’s function is to conduct forward cur-
rent, allowing sensing of the IGBT’s saturated collector-
to-emitter voltage, V
block high voltages (when the IGBT is “off”). During the
short period of time when the IGBT is switching, there is
commonly a very high dV
the IGBT’s collector-to-emitter. This results in I

this charging current and avoid false DESAT triggering,
it is best to use fast response diodes. Listed in the be-
low table are fast-recovery diodes that are suitable for
use as a DESAT diode (D
plication circuit shown in Figure 62, the voltage on pin
14 (DESAT) is V
ON voltage of D
emitter voltage). The value of V
to signal a FAULT condition, is nominally 7V – V
sired, this DESAT threshold voltage can be decreased by
using multiple DESAT diodes in series. If n is the number
of DESAT diodes then the nominal threshold value be-
comes V
diodes instead of one, diodes with half of the total re-
quired maximum reverse-voltage rating may be chosen.
