Gate Driver ICs Forum Discussions

Hi all,

Please tell me about the 1EDF5673.

I have two questions.

 1.Does 1EDF5673 have the circuit function which is similar to the active miller clamp circuit? 

     If not, please let me know the reason the function isn’t needed.

2.Is it correct that VGS is about t3(=20ns) shorter than PWM at first pulse?

    The first pulse is the light blue part below. 

Best regards,

MS

 Can't find the soldering peak reflow and also MSL documents for the 1EDN7550U gate driver on the product web page.  There is a good board assembly app note with soldering guidelines, but customer is looking for the peak reflow specification.

Please send, thank you!

I am designing a peltier controller, I will use a MOSFET h-bridge for this.
I have been reviewing many data sheets and I have a doubt, I don't know which of these gate drivers to use.
These are the options I would like to use:

a.- 2ED2103S06F
b.- WCDSC006.

I will place 4 N-MOSFET, IRF40R207, on the h-bridge.

I will use a microcontroller from the XMC1400 family that works with 5V for the PWM and the PWM will have a frequency of 5KHz, and calculate that I need a gate resistance of approximately 80 Ohms. I want to use a 12V power supply with the 2ED2103S06F, but I'm not sure if it will turn on the MOSFET fast enough running at 5KHz (it's a relatively low frequency but it's the first time I've worked with infineon's drivers) or maybe it would be better use a WCDSC006 and use a 5V supply, but according to the graph of the IRF40R207 it can handle approximately 12A with a VG of 5V, but the pelier cell that I will use consumes 8.2A and I do not think it is good that the mosfet controls a very close maximum current to the load current.
thanks for your help

I'm working with 1ED3860MC12MXUMA1 gate driver. 

I read the manual about the I2C command but without understand well. 

Is it possible to have or to receive a link where I can find information and examples about the I2C command. ??

The Gate driver doesn't work and I don't know why.... I need examples of code. I2c.

Thanks in advance

Hello,

The utilisation of the ir2010pbf is unclear for me . They is 2 GND , one for Vss (numerical partp and one for the COM (mosfet part). Does these 2 GND must be connected together or are they really isolared (like for example octocouplers).

Greatd regards , Deso

Hello there,

I am attempting to run a Altium SPICE simulation with the SPICE model for the IRS21876S, and I'm encountering a few errors. I keep getting a PWL  error about an ngspice expression not being a constant. This confused me since there is no PWL source in the model. I'm not sure if this is a problem with the model or Altium, but I thought I'd post this here to help track down the issue. I've included a screenshot of the error messages with this post.

Hi

I like the IR4426/7/8 low end drivers because they have MOSFET end stages, have two channels, and have a SO8 package. Unfortunate, the data specifications only specify the pulsed output currents. I need to know what the DC current capacity is.

Can anyone tell me what the DC output current capabilities are of these drivers, and what the RDSon resistance is of the output stage.

Thanks

Dear IFXer,

We new have following the 1ED020I12 recommended circuit to design desat function for SIC MOSFET. 

but find abnormal waveform need your help, because the issues cause the trigger the fault. And may I know the Vdesat spike root cause is what? how to avoid it? please advise us.

CH2 : Vdesat_M

CH3 : Vds_M
