EiceDRIVER™ Safe
1EDS - slew rate control IGBT driver IC
I/O signature check output terminal (5 V, CMOS-compatible)
The reference terminal for SIGO is GND1.
TST1
Terminal TST1 is a reserved terminal and has to be connected to GND1.
TST2
TST2 is a reserved terminal and has to be connected to VEE2.
VEE2
Negative power supply terminal for the output side: All VEE2 terminals must be connected to GND2, if no
separate negative supply voltage is required.
DESAT
Monitoring of the IGBT saturation voltage V_CE(sat) to detect desaturation caused by a short: The IGBT is shut
down by activating soft turn-off, if the voltage at this pin is above a given threshold. Two additional filters provide
a large robustness against noise and coupling effects. One of these filters is adjustable in terms of the filter time.
The reference terminal for DESAT is GND2.
OFF
Gate turn-off terminal in normal operation mode
The reference terminal for OFF is VEE2.
OCOFF
Input terminal to inhibit the automatic turn-off of the IGBT in case of a desaturation or current sense failure. The
fault status continues to be signaled on terminal /FLT. This feature is deactivated (internal pull-down resistor to
GND2), if the terminal is left open.
The reference terminal for OCOFF is GND2
CS
Current sense comparator input terminal for sense IGBTs or standard IGBTs with external emitter shunts.
The reference terminal for CS is GND2. If this terminal is connected to GND2, this feature is deactivated.
GATE
Input terminal for sensing the gate voltage at resistor ROFF according to Figure 3.
The reference terminal for GATE is GND2.
PRB
For preboost current adjustment connect a voltage divider between GND2 and VEE2 for a bipolar supply and
VCC2 and VEE2 for unipolar supply.
The reference terminal for PRB is VEE2.
SOFF
Output terminal for IGBT soft turn-off in case of short circuit or overcurrent events
The reference terminal for SOFF is VEE2.
GND2
Reference ground terminal of the output side.
RSENSE
Current sense feedback input of the turn-on gate current control loop.
