power transistor is fully on, the sensing diode gets
forward biased and the voltage at the DSH/L pin
decreases. At this point the biasing circuit
deactivates, in order to reduce the bias current of the
diode as shown in Figure 21.

Output stage
The structure is shown in Figure 19 and consists of
two turn on stages (connected to HOP/LOP and
HOQ/LOQ), one turn off stage for normal operation
and one turn off stage for SSD operation (both
connected to HON/LON).
When the driver turns on the IGBT (see Figure 16), a
first stage is constantly activated (HOP/LOP) while
an additional stage is maintained active only for a
limited time (t
ON1
, HOQ/LOQ). This feature boost the
total driving capability in order to accommodate both
fast gate charge to the plateau voltage and dV/dt
control in switching.
At turn off, a single n-channel sinks up to 460mA (I
O-
)
and offers a low impedance path to prevent the self-
turn on due to the parasitic Miller capacitance in the
power switch.
1.7
Voltage FeedBack
Voltage feedback pins provide information about the
state of the corresponding IGBT by means of
sensing its collector.
The V
DESAT
threshold discriminates whether the
sensed IGBT can be considered on (DSH/L <
V
DESAT
) or off (DSH/L > V
DESAT
).
IGBT state information is then sent to VFH/L
1,2,3
open collector outputs, which are tied to Vss
ground.
See Figure 22 for functional details.
