Fig. 6 Maximum cycling frequency at QGE = 1000 nC vs
temperature
The application range can be calculated by the average
output current of 20 mA and the repetetive acceptable
peak current of 2 A. It has to be considered that the curves
are valid for Qgmax = 1 µC only.
operating the SKHI 61: besides the operating voltage only
the six driver signals TOP1...BOT3 and the driver error
output signal are connected to the controller on the
primary side. The secondary side is working with the
preset VCE-threshold of 5,8 V.
Fig. 7 and 8 show examples for connection of a SKHI 71
for the application with MiniSKiiP (SKiiP 32 NAB 12) and
the following adjustments:
• Temperature monitoring of the power semiconductor
• VCE-threshold : 4,8 V
• Interlocking time : 2 µs
• Error blanking time for VCE-threshold : 4 µs
Application Hints
To adjust different VCE thresholds there is needed an
additional resistor RVCE and a capacitor CVCE for each
switch.
Gate resistor :
RG = 33 Ω
VCE-threshold resistor: intended UVCE = 4,8 V
Applying equation 1 RVCE will result in
RVCE[kΩ] = 5---,--4-------1--0-1--,-,9--8-3--6---⋅---4---,--8- – 4,75[kΩ ] = 7,9kΩ
Next value taken from the E24-range: 8,25 k. The
threshold voltage is recalculated with 8,25 kΩ.
VCE-threshold at 4,82 V.
For the capacitor the blanking time may be calculated as:
tblanking = 4 µs
CVCE[nF] = (---8-4--,--2-⋅--5-(--7-+--2---4,--7-,-7-5--5--+--)---8⋅---,3--2-6--5-,--0)---8- – 0,1 = 590pF
Thus there can be chosen a capacitor of 680 pF.
