Gate Driver ICs Forum Discussions

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 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

いつもお世話になっております。

Gate Driver（1ED3491MC12M）の出力電圧スペックに関して、アドバイス頂ければと思います。

データシートP34記載の「High level output voltage」ですが、Vvcc2+0.87 Vとあります。

出力電圧が電源電圧よりも上がるのはなぜでしょうか？

お手数かけ致しますが、ご教示頂ければと思います。

以上、宜しくお願い致します。

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

Hi community, hi Infineon support,

we are planning to use the AUIR324x IC gate driver for a battery switching architecture with current constraints of

15A continous, 20A for 2mns, 30A for 10s. We have been testing the "AUIR3241S/AUIR3242S - Board Back to Back 12V" with the batteries and it seems to switch correctly between the 2 batteries.

However at this time we have 2 questions :

- technical : attached TEK0000 (GPIO, Load - resistive electronic 150W load - voltage switching from BAT1=13V to BAT2=20V in ~30us) we can see a first intermediate voltage level for 10us then a small peak at 25V before reaching 20V. Could you explain the signal ?

- commercial : we don't see any stock for AUIR324x IC chip and we want to design a PCB around September. What is the expected planning for procurement of this chip ?

Xavier.

Hi there,

As topic, I have went through the whole manual but there is nearly no description about these ov uv err:

The most related info I can find is the supposed voltage supply range for the shunt amp in table 19, is this the checking condition?:

Have I missed anything? Also what is their corresponding failure behaviour? Again there is no description in manual at all!

Thanks for reading, any reply is appreciated.

Hello infineon I am Kim, a student studying in Korea.
One challenge was encountered while implementing a motor drive system.
IPTC015N10NM5 is used as a switching element and 6EDL04N02PT/DSO-28 is used as a gate driver.
pwm is normally input up to the inputs (HIN1, HIN2) of the gate driver, but if you observe the output terminals HO1 and LO1 with an oscilloscope, you can observe the non-sinusoidal output as shown in the attached picture.
Also, as a result of checking VB1 and VS1, there was nothing wrong with 15V.
I don't know which part is the problem, so I'll attach the circuit diagram.
Please help me.
