4 Functional Description
1EDI EiceDRIVER™ Compact
Separate output variant for IGBT
Functional Description
4.1 Introduction
The 1EDI EiceDRIVER™ Compact is a general purpose IGBT gate driver. Basic control and protection features
support fast and easy design of highly reliable systems.
The integrated galvanic isolation between control input logic and driving output stage grants additional safety. Its
wide input voltage supply range support the direct connection of various signal sources like DSPs and
microcontrollers.
The separated rail-to-rail driver outputs simplify gate resistor selection, save an external high current bypass diode
and enhance dV/dt control.

4.2 Supply
The driver can operate over a wide supply voltage range, either unipolar or bipolar.
With bipolar supply the driver is typically operated with a positive voltage of 15 V at VCC2 and a negative voltage
of -8V at GND2 relative to the emitter of the IGBT as seen in Figure 4. Negative supply can help to prevent a
dynamic turn on due to the additional charge which is generated from IGBT’s input capacitance.
For unipolar supply configuration the driver is typically supplied with a positive voltage of 15 V at VCC2. In this
case, careful evaluation for turn off gate resistor selection is recommended to avoid dynamic turn on (see
Figure 5).
