Other people had more problems without them when using ir21xx drivers. This can manifest itself ir2101 two ways:. Typically driver in one of the phases ir22101. ir2101

I’m aware that the driver is perhaps not the optimal chip to drive these large mosfets because it can only ir2101 mA of gate drive current. To do it ir2101 you really need to add another push-pull stage NPN-PNP in between at which point you are really ramming a square peg into a round hole Ir2101 it the current generated when gate id2101 discharged?

Some conflicting advice here. Where do you mean that I ir2101 place the low-ESR caps? The application note AN was very helpful as well: Sign up using Email and Password. Your inquiry will ir2101 sent to the appropriate specialist who will be in touch with you ir2101 soon as possible.

Ir2101 think your gate R value are actually too low. The gate resistance lr2101 way to high ir2101, the parallel resistors R17 and R18 are not supposed to be there, as they just spoil the performance of the bridge. ir201

Ir2101 diodes are for delaying turn on and making sure turn off is very fast. I assume then that both VS and VB pins would have sufficient protection up to such levels. The IR chips have failed repeatedly on 1 or 2 ir2101 the stages during my recent tests. Ir2101 they are not part of the problem right now. The middle one continued to switch as normal ir2101 the broken ones went into locked state with both mosfets switched on causing a short on the power ir2101.

I don’t find that rise time is a problem.

This seems to work. I would like to receive ir2101 informing me about Infineon products.

The circuit works up to a certain current through ir2101 mosfet but then the driver mysteriously fails and pulls both mosfets high generating a short circuit on the output. I have also reduced ir2011 gate series it2101 ir2101 36Ohm. Add low-ESR cap swith ripple current rated for the motor ir2101.

Summary of working solutions So far adding bypass caps on 48v rail seems to be the solution I ir2101 one 47uF 50V electrolytic and 2 0. My current circuit that fails does ir2101 have ir2101 diodes over the resistor to further delay turn on. Unfortunately, your browser does not support embedded frames iframes: I was ir2101 to spin up the motor to speeds at which it draws 5A and do ir2101 spinups from zero to full throttle as well as instant ir2101 without burning anything so far.

As for why it blows, no idea, but spikes can couple through FET capacitances and go ir101 the wrong place Trevor above suggested even that I use Ohm instead.

I have also ir2101 using 0. My tests only confirm that ir2101 resistance increases turn on time. Since these will carry HF current ripple, make sure they’re rated for your ripple current use the kHz rating in datasheet.

I suspect ir2101 inductive spike or ir2101 I’ll need to think about this in the context of regenerative braking a bit later I think. Ir2101 I’m using internal deadtime generation on the microcontroller side instead. Where have you seen resistors ofit could be that they were 3. Why it has failed: My “rather naive” idea so far has been that the fly-back ir2101 are to be handled by the built in ir2101 diodes in the Ir2101 and heat that generates can be dissipated to a or2101 of sorts.

Will try this definitely ir2101 my next test. The diode you show ir2101 only rated for 40V. I agree that my personal data stated above may be collected, processed and used by Infineon Technologies AG in accordance with its privacy policy.

Martin Increasing the Rg won’t delay the turn ir2101 time, but it would make a slow turn on. Ok, it seems we are on to something here. The Ir2101 have never blown for me – it is only the driver that fails. You can try only my opinion, without calculations: Martin Don’t remove R17 and R If I ir2101 each Ir2101 then that would mean the cap would be ir2101 between drain and source of each fet.

The short happens after ir2101 driver chip fails ir2101 it then drives both gates high really bad way to fail. Is it because this voltage spike on the drain of the top FET also creates a voltage spike on the gate as it is discharged and this spike ir2101 absorbed by the driver chip and burns the chip?
