Figure 26. HCPL-3150 Typical Application Circuit with Negative IGBT Gate Drive.
Selecting the Gate Resistor
(Rg) to Minimize IGBT
Switching Losses.
Step 1: Calculate Rg Minimum
From the I
OL
Peak Specifica-
tion.
The IGBT and Rg in Figure
26 can be analyzed as a simple
RC circuit with a voltage supplied
by the HCPL-3150.

The V
OL
value of 2 V in the pre-
vious equation is a conservative
value of V
OL
at the peak current
of 0.6 A (see Figure 6). At lower
Rg values the voltage supplied by
the HCPL-3150 is not an ideal
voltage step. This results in lower
peak currents (more margin)
than predicted by this analysis.
When negative gate drive is not
used V
EE
in the previous equation
is equal to zero volts.
Step 2: Check the HCPL-3150
Power Dissipation and
Increase Rg if Necessary.
The
HCPL-3150 total power dissipa-
tion (P
T
) is equal to the sum of
the emitter power (P

output power (P
