Hi,
Thanks for your patience
The Eval-1ED3890Mx12M evaluation board is designed to be used by design engineers to evaluate the
1ED3890MC12M or 1ED3890MU12M EiceDRIVER™ isolated gate driver IC in a half-bridge configuration.
The board is designed to be used in conjunction with EiceDRIVER™ Eval-1ED38x0DCT microcontroller board, in
order to easily configure all the parameters
Prerequisites are:
• PC with Windows 7 or higher with Infineon XMC USB driver installed
• EiceDRIVER™ 1ED38x0 DCT software installed
• USB A to micro-USB cable
• EiceDRIVER™ Eval-1ED38x0DCT microcontroller board
• Suitable power switches assembled in the sockets T50 and T60. E.g.: IKW50N120CS7 TRENCHSTOP™ IGBTs
or IMW120R030M1H CoolSiC™ SiC MOSFETs
• Assembled external high-voltage decoupling capacitor (100 µF) across the high-voltage power terminals:
X90-1 (P1000VP) and X90-3 (GND)
• Low-voltage power supply for supplying primary-side power supply circuit, capable of supplying 15 V,
100 mA (P15VP, SGND)
• High-voltage power supply for supplying the power stage between X90-1 (P1000VP) and X90-3 (GND)
• A suitable inductive load for double-pulse testing
In the evaluation board, if the clamp or clamp driver functionality is not needed, the CLAMP ADC can be used to
measure a thermistor on the PCB for the high-side gate driver, or to sample the DC-link voltage through a
voltage divider for the low-side gate driver. By default, the evaluation board comes with the circuitry
configured for the CLAMP pin to be used as a clamp pre-driver, and is designed to be easily reconfigured. The
hardware changes required to adjust the CLAMP pin as a clamp, clamp driver and ADC for NTC or DC-link
measurements
For the high-side gate driver, the adjustment is done via R52, R53 and R56, marked in Figure below. R56 is placed on the bottom side of the PCB.
For the low-side gate driver, the adjustment is done via R62, R63 and R95
To evaluate ADC function, For the high-side gate driver, the 0 Ω resistor should be moved to R56 and in order to improve noise immunity, C58 can be populated. Similarly, for the low-side, the 0 Ω resistor should be moved to R95. To improve noise immunity for the DC-link measurement, capacitor C95 can be used in combination with a higher resistor value to create an RC filter
Power-up sequence:
1. Connect the EiceDRIVER™ Eval-1ED38x0DCT to the connector X1 of the EiceDRIVER™ Eval-1ED38x0DCT via
the ribbon cable.
2. Connect the EiceDRIVER™ Eval-1ED38x0DCT via the USB cable to the computer used for configuration.
3. Ensure that jumper J30 is open in order to have the built-in power supply enabled.
4. Connect one end of the inductive load to terminal X90-2 (PHASE) and the other end, depending on the
double-pulse test requirements, to either X90-1 (P1000VP) or X90-3 (GND) for low-side or high-side testing.
5. Supply the input side power supply, P15VP, at connector X45 with +15.5 V and ground.
6. The green LED D46 (15V_ok) will turn on to signal the input supply is present.
7. The green LED D40 (VCCC1_ok) will turn on to signal the primary side supply of the gate driver is present
8. The green LED D41 (FLT#) will turn on, signaling there is no internal fault registered in the gate driver.
9. The red LED D44 (RDYC) will turn on, signaling the gate driver is not configured.
10. Start the EiceDRIVER™ 1ED38x0 DCT and configure the gate drivers (see Chapter 2.3)
11. Connect the high-voltage supply to connector X90-1(P1000VP) and X90-3 (GND).
When the software is started with the EiceDRIVER™ Eval-1ED38x0DCT board connected to the computer, the
screen in below Fig appears, which is main window.
The guided configuration mode is chosen by clicking on the green button in Figure above and will provide a
detailed explanation of each configurable parameter. Afterwards, each of the 49 setting windows can be
navigated through, either by using the drop-down menu or by using the navigation
buttons. refer below Fig.
advanced configuration mode is entered by clicking on the magenta button in main window. Below Fig. shows the window of the advanced configuration mode.
Each of the adjustable parameters are grouped into eight tabs based on their main function. The last tab, Register View, can be used to observe the registers’ hexadecimal values for the high-side and low side gate drivers. The register view can also be used to save the current registers’ configuration as an XML file,
load a previously saved configuration, transfer the configuration to the gate driver, or read the current
registers’ configuration in the gate drivers.
After adjusting the settings on each of the settings tabs, the impacted registers are shown with their new value. By using the DT button or GT button, the settings can be pushed to the active gate driver, or to all the connected gate drivers, respectively. Before moving to another section, all the changed settings have to be pushed to the gate driver, by using one of the two buttons.
I have briefed you about the configuration. Please go through User Guide for detailed explanation.
