SCALE Driver
2SD315AI-33 Data Sheet
Double or multiple pins
Due to the high output currents, several pins are present in duplicate or as multiples. It
is recommended to connect these in parallel on the layout so that the voltage drop
across the lead frames (contact pins) is minimized.
Special terminal pins
The 2SD315AI-33 half-bridge driver is optimized for universal use and high driver
performance and thus contains more terminal pins than the compact SCALE drivers.
These pins will be described below:
Visox and COMx pins: external support capacitor
Note: The “x“ in Visox and COMx stands for the channel number.
Like the compact SCALE drivers, the 2SD315AI-33 also has blocking capacitors on the
secondary side of the DC/DC converter for each drive channel. IGBTs with gate charges
up to 3 C (corresponding typically to about a 1200V/300A module) and gate currents
up to about 10A can be driven without external blocking capacitors. At higher gate
charges or gate currents, external blocking capacitors are required between Visox and
COMx. These capacitors should be rated at between 47 and 120 F (but no more than
220
F) and a dielectric strength of
20V. It is important that the capacitors are
suitable for switched-mode power supply applications (low inductance and high current
handling capacity). They must be connected as close as possible to the driver’s terminal
pins with minimum inductance.
The anode of the capacitor is connected to Visox, its cathode to COMx. The COMx pin is
always present in duplicate.
VDC and GND pins: supply for DC/DC Converter
It is recommended to connect a blocking capacitor of approximately 220µF to the driver
input. This capacitor should also be of the switched-mode power supply type.
Pin LSx: Local status
Note: The “x“ in LSx stands for the channel number.
The status of the IGD 001 for each channel is available at this output. It is an open-
collector output to which approximately 5mA may be applied. A LED can be connected
here, for example, as shown in Fig. 6. The LED lights up in normal operation
