2.2 EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS overview
The EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS is a high voltage IGBT/SiC driver for automotive motor
drives with a power above 5 kW. The device is based on Infineon's Coreless Transformer (CT) technology,
providing galvanic insulation between the low voltage domain and the high voltage domain. The device
supports 400 V, 600 V and 1200 V IGBT/SiC technologies.
The primary logic of the device supports 5 V and 3.3 V.
The high voltage domain (secondary side) can drive IGBT/Sic power switches directly or an external booster
stage. Short propagation delay and controlled internal tolerances lead to minimal distortion of the PWM signal.
The device features a high output stage current of typically 10 A. The integrated Miller clamping stage with
typically 10 A allows unipolar supply of the IGBT/SiC power switch.
The device supports functional safety requirements at system level according to ISO 26262. The safety related
features ease the implementation of a transition to safe state.

3 Getting started
The EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS evaluation board is recommended to be used with the
HybridPACK™ DSC or the AIMW120R045M1 CoolSIC™ MOSFET mounted. It can also be used in capacitive load
emulation or with any other footprint compatible device. For load emulation place capacitors C22 and C7, see
Figure 5, which are not placed by default.
With capacitive load emulation the DESAT protection triggers on every switch-on event, so the device enters
error mode, see Operating modes. In order to suppress such unwanted triggering of DESAT protection, connect
DESAT_T to GND_2T and DESAT_B to GND_2B, respectively. Each DESAT_x signal can be accessed via the
respective test point.
Figure 5 C22 and C7 PCB mounting location
To toggle the gate driver output, perform the following steps:
1. Provide the primary supply voltage according to Operating conditions.
2. Set jumpers according to Table 4.
3. Verify that VCC1 and VCC2 voltages are present by checking the LED indicators.
4. Press the RESET button to perform a transition of the drivers from Power_Down to Normal_Mode, see
Operating modes.
5. Verify that the device is in Normal_Mode: RDY LEDs on, and NLFT LEDs o.
6. Apply a PWM signal to either INP or INN according to Operating conditions to start toggling the high side
or low side switch, respectively.
7. If the device enters Error_Mode switches o the output stage due to a triggered protection feature, then
press the RESET button to perform a transition to Ready_Mode and Normal_Mode.
The high side driver and the low side driver interlock each other by crossing the INP and INN signals, see
Schematic. So when one of the drivers is commanded to switch on, the other one is automatically kept o,
regardless of the respective input signal. This feature prevents unintended shoot-through in case both input
signals command switching on of both drivers at the same time by accident.

4 Evaluation board
4.1 PCB overview
Figure 6 shows an overview of the EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS evaluation board. A vertical
line on the PCB marks the split between primary side and secondary side. The assembly applies for all variants
of the EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS evaluation board, except for IC1 and IC2, which are
specific to each variant, see Table 2. The transformer TR1 near the center of the PCB provides the supply
voltages for the secondary side of the gate drivers.
Power switches, such as the HybridPACK™ DSC or the AIMW120R045M1 CoolSIC™ MOSFET are not included and
can be ordered separately. As an alternative, a PG-TO247-3 compatible power switch can be mounted.
Figure 6 PCB overview
When using the AIMW120R045M1 CoolSIC™ MOSFET or a PG-TO247-3 compatible power switch, an external heat
sink option exists. The PCB footprint is prepared to mount the WA-T247-101E from Ohmite. the configuration is
shown in Figure 7. The heat sink is not included by default and can be purchased separately.

4.2 Connectors
There are connectors on the primary side and on the secondary side of the EiceDRIVER™ enhanced 1EDI302xAS/
1EDI303xAS evaluation board. The board requires a supply voltage of 15 V at the banana sockets on the primary
side. The BNC connectors INN and INP accept the PWM signal for the input of each driver, see Figure 8.
Figure 8 Primary side connectors
Figure 9 shows the secondary side screw terminals for the secondary supply voltage and the center tap of the
half bridge.

4.3 LED indicators
LEDs on the EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS evaluation board indicate board health and driver
status, see Figure 10:
1. Dedicated NFLT_x and RDY_x indicator for each driver
2. Primary side supply indicator on VCC1
3. Secondary side VCC2 indicator for each driver
If the driver pulls the NFLT_x signal to "low", then the NFLT-x LED is on to indicate a fault.
If the driver does not pull the RDY_x signal to "low", then the RDY_x LED is on to indicate that the device is ready.
The status indicated by the NFLT_x and RDY_x LEDs can be used to determine the current operating mode, see
Operating modes.

4.5 Configuration
The EiceDRIVER™ enhanced 1EDI302xAS/1EDI303xAS evaluation board can be configured via jumpers on the
board. The board provides the following configuration options for each driver:
1. ENABLE_x
2. ASC pull-up
3. OCP disable
4. AIP signal selection
The reset button R triggers a power-on reset of both drivers and clears the Error_Mode, see Operating modes.

4.5.1 Jumper on Enable_x
Place the jumpers on ENABLE_B and ENABLE_T to enable each driver respectively. Figure 12 shows the location
and the schematic symbol of the ENABLE_B jumper. If no jumper is placed, then an internal pull-down resistor
pulls ENABLE_x to GND.
Figure 12 ENABLE_B jumper (low side driver example)
4.5.2 Jumper on ASC_x
Place this jumper on the 1EDI3021AS and 1EDI3031AS variants to enable the secondary side ASC. Secondary
side ASC overrides the INP signal on the primary side and drives the gate to "high".

Overcurrent detection can be disabled by placing the jumper that connects OCPP to OCPN. The overcurrent
detection feature requires the HybridPACK™ DSC module to be mounted.

4.5.4 AIP_x signal selection jumper
The AIP_x signal selection jumper is only relevant for the 1EDI3020AS, 1EDI3023AS, 1EDI3030AS, 1EDI3033AS
variants. The jumper can be placed in two configurations. It is used to select an external circuit connected to the
AIP_x pin. Figure 15 shows the schematic and the location is shown.
Placing the jumper between pin 1 and 2 connects several bipolar transistors in diode configuration to emulate
temperature measurement on the 1EDI3020AS and 1EDI3030AS. These devices have an internal current source
combined with the ADC.
Placing the jumper between pin 2 and 3 connects a voltage divider to VCC2 with an NTC inside. This can be used
to evaluate NTC based temperature measurements on the 1EDI3023AS and 1EDI3033AS devices. The internal
current source on these devices is deactivated for the ADC. For details on all device variants please refer to the
datasheet.
Do not place the jumper when the HybridPACK™ DSC is soldered to the board. In this case the ADC is
automatically connected to the module's internal diode structure for temperature measurement.
Figure 15 AIP signal selection jumper (bottom side example)
If the NTC configuration is used and the device is in Ready_Mode or in Error_Mode as shown in Operating
modes, then the output duty cycle at the DATA pin can be calculated according to Equation 1.
