Hello

We are using the P channel MOSFET IRLM5103 two switch the 12V for the analog Application. the voltage is switched from Source to drain when the MOSFET is ON.  Also when there is 154V volt at the input (Drain) then there will be 12.5V constant at the output (Source) of the depletion mosfet. due to which the the body diode of the IRLM5103 will be the forward biased and the some of the current will flow to the +12V source. how much current will flow through the body diode when that body diode will forward biased ? what will impact on the +12 Source ?

I have attached the schematic of the application.

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

Hi,

I am connecting up the iMotion-Link for the first time. I understand from my previous post (see link below) that I can use 5V logic on the target board.

https://community.infineon.com/t5/iMOTION-controller-driver-IPM/iMotion-Link-useable-for-interfacing-with-custom-board-with-IMC101TF-and-5V/m-p/346143/thread-id/436

However, now that I am using the iMotion-Link, I am not getting ANY signal out the RXD1 pin (which should transmit to the IMC101's RX0 pin on my board).  Both RXD1 and TXD1 pins from the iMotion-Link 8-pin header connector appear to be floating. Of course, the 3.3V switch is turned off as well.

I hook up the USB cable between PC and the iMotion-Link, run MCEDesigner, the virutal serial port appears (as COM10) and then I try to connect over the port. However, no signals are generated from the RXD1 and TXD1 pins.  What could be going wrong?

Do I need to apply my 5V power to the 3.3V pins on the header connector?  I thought that RXD1 pin would be driven without needing this.

I also verified that resistor R1 is not present on the iMotion-Link per previous posts on this issue. I purchased the unit earlier this year.

Thanks,

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.

I am currently using a setup with a FF1400R12IP4 IGBT with a corresponding 2SP0320TA0 gate driver. I have verified that the diodes are working in the intended direction with the description below.

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

Hello

I designed the motor driver using the IC controller IMC102 and switch IFCM15P60GD for the motor PMSM with Power 750W, and in practical testing, at the time of connecting the AC input and in some cases during the operation Short ciruit between pin collector to emitter in IFCM15P60GD (Pin 22 , 23) and it fail , 

The diode that I put on the fiber in parallel with the body diode of the switch PFC is part number BYG20J ,Is my choice correct? Can it be the cause of damage to the PFC switch or may it be another reason?

board specifications

Input Voltage 165 - 265 Vrms  AC input
Input current 3 Arms input 220 VAC, IFCM15P60GD

Current per leg 2.1 Arms input 220VAC 

DC bus voltage 400 V

PFC switching frequency 50 kHz

Inverter switching frequency 15 kHz

PFC current sensing resistor 25 mΩ

Inverter current sensing resistor 50mΩ  (Single Shunt)

What solution do you suggest?

Best Regards.
