The board is available from Infineon in sampling quantities. The properties of this part are described in the datasheet chapter of this document, whereas the remaining paragraphs provide information intended to enable the customer to copy, modify and qualify the design for production, according to their own specific requirements. The design of the EVAL_6EDL04N02PR was performed with respect to the environmental conditions described in this document. The design was tested as described in this document, but not qualified regarding manufacturing, lifetime or over the full ambient operating conditions. The boards provided by Infineon are subjected to functional testing only. Due to their purpose Evaluation Boards are not subjected to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products. These Evaluation Boards are used for development support only and should not be used as reference design for volume production. See Legal Disclaimer and Warnings for further restrictions on Infineons warranty and liability.

The evaluation board does not provide an over voltage supply monitoring, therefore the user has to ensure that the voltages are in the correct range. Voltages above the max. values will lead to damages of the MOSFET driver. The availability of the supply voltages is visible over the green status LEDs. The high-Side gate driver outputs are supplied over internal bootstrap diodes and the bootstrap capacitors CBOOT1,2,3. To ensure that the bootstrap capacitor is charged before the high side MOSFET is switched on, the low side MOSFET has to be switched on for a dedicated time. 3.2 Under voltage lockout The +15V supply VCC is monitored by the 6EDL04N02PR. In case of an undervoltage the driver output is switched off. The thresholds are typically VCCUV+ = 9 V (positive going) and VCCUV– = 8.1 V (negative going). This status is visible over the red FAULT LED. If the FAULT LED is on and the OC LED is off, an undervoltage is detected. 3.3 Over-current detection The 6EDL04N02PR provides an over-current detection function by connecting the ITRIP input with the load feedback current. The shunt voltage drop is connected to the ITRIP comparator which has a threshold of typically 0.44V. With the Shunt resistor value of 20mOhm the ITRIP is triggered at a current of typically 22A. The over-current event generates a hard shut down of all gate driver outputs and provides a latched fault feedback at /FAULT pin and the capacitor at pin RCIN will be discharged. The fault is latched till the capacitor at RCIN is re-charged and the voltage level reaches a value of typically 5.2V. In the EVAL_6EDL04N02PR a logic keeps the capacitor at RCIN discharged till a LOW pulse at the RESET pin occures. An over-current event is shown by the LED “OC” and LED “FAULT” together. At power up the logic has an undefined state. If only the LED “OC” is on after power up it is recommend to reset the logic with a LOW pulse at RESET. The shunt resistor value may be adjusted, when operating the board with different HV supply voltage in order to guarantee a proper detection of short circuit events. Application Note 9 Revision 1.0, 2013-07-26 EiceDRIVER™ Driver IC Evaluation Board EVAL_6EDL04N02PR Application Note Electrical features IC ITRIP ~0.44V MOSFET gate is switched off ITRIP VGS_bot RCIN RCIN goes low Figure 3-1 over-current detection signals during shoot through (Ic curve with 1.2µs delay due to slow current probe) 3.4 MOSFET turn - on / off The switching characteristic of the MOSFETs is defined by the gate resistors RGxONT, RGxONB, RGxOFFT, RGxOFFB and the diodes DGxT and DGxB. Where “x” means 1,2,3 for the three output stages. Figure 3-2 gate driver output of the 6EDL04N02PR. Exemplarily only output 1 pictured The gate resistors are adapted to the max. gate driver output current of the 6EDL04N02PR for turn-on and turn-off. There is the possibility to adapt the switching characteristic to specific applications or to different MOSFETs by replacing the resistor values. The use of RGxOFFT and RGxOFFB together with DGxT and DGxB makes it possible to change the on-switching and the off-switching slopes of the MOSFET independent to each other. To avoid a shoot through between top- and bottom MOSFET, the operator needs ensure sufficient dead time. With this setup the deadtime should be > 0.5µs.

If a bigger DCLink capacity is necessary it has to be connected externally to the connectors V+HV and GND_HV. 3.6 Input Signals Figure 3-6 Driver input Signals There is the possibility to use low pass filters inside the PWM input signals LIN1,2,3 and HIN1,2,3 to avoid an undesired switch on an MOSFET by disturbances. This feature is not used in this evaluation board, but there is the possibility to test it by changing the resistors RIN1,2,3,4,5,6 and the capacitors CIN1,2,3,4,5,6.
