HIGHER OUTPUT CURRENT USING AN EXTERNAL CURRENT BUFFER
To increase the IGBT gate drive current, a non-inverting current buffer (such as the npn/pnp buffer shown in
Figure 72) may be used. Inverting types are not compatible with the desaturation fault protection circuitry and
must be avoided. The MJD44H11/MJD45H11 pair is appropriate for currents up to 8 A, the D44VH10/ D45VH10
pair for up to 15 A maximum.
