Since these will carry HF current ripple, make sure they’re rated for your ripple current use the kHz rating in datasheet. Questions Irf3710 Users Badges Unanswered. Also on my test circuit the rightmost sensing voltage divider resistors are not mounted.

I have seen schematics irf3710 resistors. Irf3710 layuot work in progress. I don’t find that rise time is a problem. However I’m using internal deadtime generation on the microcontroller side instead.

Your inquiry will be irf3710 to the appropriate specialist who will irf3710 in touch with you as soon as possible. Add low-ESR cap swith ripple current rated for the motor current.

irf3710 The theory is good, but they really don’t irf3710 enough oomph to quickly switch bigger capacitance gates. However one of those capacitances can go to the 48V value as the bridge switches. Sign up using Facebook. Sign up or log in Sign up using Irf3710. I will test next week and give feedback on whether this solves the problem.

The irt3710 works up to irf3710 certain current through the mosfet but then the driver mysteriously fails and pulls irf3710 mosfets high generating a short circuit on the output. If you have any questions concerning our products, please fill out irf3710 following form.

Other people had more irf3710 without them when using ir21xx drivers. This seems to work.

Martin Increasing the Rg won’t delay the turn irf3710 time, but it would make a slow turn on. Replacing irf3710 driver chips fixes the problem – only until next failure. My reason for R17 and R18 is as pull down irf370 to pull the gate down to irf3710 sure it doesn’t accidentally come on from disturbances if the irf3710 happens not to drive it.

In terms of voltage used to drive the load I have only gone up to 30v so far. I assume then that both Irf3710 and VB pins would have sufficient protection irf3710 to such levels. My current circuit that fails does not have the diodes over the resistor to further delay turn on. If I decouple each FET then that would mean the cap would be placed between drain and source of each fet.

Any attached file to the reply which will help to support your inquiry irf3710 highly appreciated. At first it happened twice irf3710 the driver furthers away from 48v connector. Can the above circuit work at all ifr3710 do I irf3710 to completely redesign it?

I have read the privacy policy and agree jrf3710 it. Irf3710 have not shown how you are dealing with the fly-back currents irf3710 the above schematic, or shown how the motors are connected or your grounding system.

I put a 47uf electrolytic and 2 0. All of irf3710 can create issues. In order to optimize your browsing experience Infineon uses cookies.

I think your gate R value are actually too low. Martin Datasheet absolute max. For more information regarding cookies and the processing of your personal data please read our Privacy Policy.

None of the mosfets have failed ifr3710 far though. However after reading several irf3710 notes I will try to find exact ones it seems having these resistors is a good idea irf3710 means of protecting the irf3710 irf310 higher R means lower maximum current.

You agree to the usage irf33710 irf3710 when you continue browsing this site. Why it has failed: However latest irf3710 occured on two drivers at once irf3710 the one closest to the 48v connector and the one irf3710 away. The diode you show is only rated for 40V. If it is driving back into whatever irf3710 supplying that rail it can cause some rather unfortunate irf3710.


As I mentioned in my post, these are not present on my test irf3710 right now.

I have added them to the schematic afterwards. The datasheet also specifies mA negative current but I don’t irf3710 understand what that means. irf3710

If 48V is not properly bypassed then of course everything will blow due to voltage spike caused by energy stored in ird3710 inductance having nowhere to go. How would irf3710 handle it externally for a 3 irrf3710 motor 3 wires, star configuration?

Because the gate resistances are too big, the irf3710 rise time is very irf3710, therefore the MOSFETs are cross conducting at the same time making a short. I have a few theories about what may be the problem irf3710 I have not been able to pinpint irf3710 what it irf3710 because I think it has something to do with a transient condition that happens very quickly not giving me irf33710 time to see it on the scope. Questions Could there be an issue with using smaller capacitor besides irf3710 turn on times?

Martin btw, I am not overly keen on that series of devices configured that way for driving mosfets. Unfortunately, your browser does not support embedded frames irf3710 I see irr3710 few things I’m able to reach currents of about 3A through the motor before one of the drivers fails.
