Hi

I have 3 gate drivers 2ED4820-EM. On all 3 I can individually switch channel A without any issues. But on all 3 channel B reports ITRIP as soon as I set it to ON. Edit: it reports ITRIP on the one chip I want to set to ON, but all 3 have the same behaviour.

I cant figure out what the problem is. I already posted my design here and it seems ok. I played around with filter and blank times but no success.

Furthermore I can see on the osciloscope that the channel tries to switch on but immediately turns off again. I apply the same load which works on channel A.

Any help is highly appreciated.

Thanks

Andy

This is about the gate driver of 2ED2181S06F.

This is an existing product with a built-in bootstrap diode, but does it also have a limiting resistor built into the bootstrap diode path?

I checked the datasheet, but I couldn't understand it. If there is a built-in bootstrap resistor, why does it have a wide range of 15Ω at minimum to 45Ω at maximum as stated in the data sheet?

f anyone knows the details, please respond.

Hello, 

I am trying to study the 1k6W PSU Link .
I am unable to understand the connections of Oring MOSFET gate driver (secondary side), specifically  "VCC2" and "GND2"

The VCC2 pin is connected to 12V flyback auxiliary net "Oring VDD2" and the net "Oring VDD" of LLC transformer through a Schottky diode and the GND2 pin is connected to net "12Voring".

First of all, I want to know, what is the need for diodes "D8" and "D17"? Please clarify.

Also, kindly specify why an isolated gate driver 1EDI20N12AF is required for Oring MOSFETs, whereas a non-isolated gate-driver 2EDN7524F is used for Synchronous MOSFETs.

Please find the reference image attached.

Hello All,

We are using 1ED020I12-F2 gate driver for driving three phase inverter with 6 IGBT modules and each IGBT module is being driven by 1ED020I12-F2 gate driver.

We are using single (i.e. unipolar power supply) of +15V. I am assuming that as this IC has feature of Active miller clamp which will prevent dv/dt turn on failure and hence there is no need to give bipolar i.e. -ve  supply also.  Am i correct with this?

Question is as we have not used negative power supply is it ok ? or do you have use cases with 1ED020I12-F2 gate driver with only positive power supply and up to what rating of IGBT module.

Pls suggest.

Regards,

Mukesh

I would like to do a simulation that includes the current sense amplifier.
Unfortunately, it is not included in the TLE9210x-232QX PSpice Simulation Models available in Design Support.

Please introduce the most suitable PSpice Simulation Models.
It would be better if you could do Monte Carlo analysis.

Vinp is pulse source with 3V amplitude. there is no output at OUTB.

do you see any error on simulation schematic that stops 2EDF8275 to give OUT B output?

Hello

Do you have  alternate device or solution for ir2520dpbf? (obsolete)

This product seems special , so that  I could not find  alternate...

Please advise.

Thank you

I want to know whether the resistor used in the HIN and LIN is a pull-down resistor or resistor used for limiting the current to the input pins. (Reference EVAL-2ED1324S12PM1)

Hello everyone,

I am working with the 6ED2231S12TM1 with the IMC101 in order to drive a FP75R12N2T7BPSA1.
The 6ED2231S12TM1 is rated for current +0.35A / -0.65A (source/sink).
Due to the high gate charge of the PIM I believe that I need more current.

This is the schematic I made:

I used the ZXGD3006E6Q wich is a normal push-pull gate driver.
This is connected between the 6ED and the PIM in this way:

Is this a valid way to increase the current capability of the 6ED?

Kind regards,

Marco Negrini
