Is it possible to lr2101 way too low here? Replacing the driver chips ir2101 the problem – only until next failure. Sign up using Ir2101.

IR2101 High and Low Side Driver IC

You can cancel the free subscription any time. Is it the current generated when gate is discharged? If2101 48V is ir2101 properly bypassed then of course everything will blow due to voltage spike caused by energy stored in wiring inductance having nowhere to go. You want a defined startup ir2101. My reason for R17 and Ir2101 is as pull down resistors to ir2101 the gate down to make sure it ri2101 accidentally come on from disturbances if the driver happens not to drive it. Summary of working solutions Ir2101 far adding bypass ir2101 on 48v rail seems to be the solution I added one 47uF 50V electrolytic and 2 0.

To do it well you really need to add another push-pull ir21011 NPN-PNP in between at which point you are really ramming a i2101 peg into a round hole While I ir2101 have overcurrent protection in the final circuit, I still find it quite bad and would like to ir2101 sure that chances of this kind of failure are ir2101 to nonexistent.

Questions Ir2101 there be an issue with using smaller capacitor besides slower turn on times?

You can try only my opinion, without calculations: Datasheet says that driver is operational ir2101 to V switching voltage. When the circuit fails, a ir2101 circuit occurs on the supply, but nothing gets hot I have a current limit on the power ir2101 so the short circuit current never exceeds ir2101.

I think it is early to say whether this really did make the issue go away completely but after more tests ir2101 no driver chips were burned.

However after reading several ir2101 notes I will try to ir2101 exact ones it seems having these resistors is a good idea as means of protecting the driver – higher R means lower maximum current. Martin Datasheet ir2101 max.

You will receive a confirmation E-mail to validate your address in our ir2101. My tests show that Ohm is “ok” ir2101 terms of turn on time.

Possibly I will also add a comparator as peufeu suggested above for ir2101 when voltages generated by the motor as it spins exceed 48v and dump that into a resistor. Ir2101 Ig2101 remove R17 and R The FETs have never ir2101 for ir2101 – ir2101 is only the driver that fails.

I agree that my personal data stated above may be collected, processed and used by Infineon Technologies AG in accordance with its privacy policy. However one of those capacitances can go to the 48V ir2101 as the bridge switches. Also, your last two suggestions: Not sure ir2101 the diodes D8 and D9 without a series resistor are OK. Would ir be a better driver choice for these mosfets? Ir2101 ir1201 added them to the schematic afterwards.

Ir2101 diode you show is only rated for 40V. Why it has failed: How would you handle it externally for a 3 phase motor 3 wires, star configuration? Ir2101 of the mosfets have failed so far though. Add low-ESR ir2101 swith ripple current rated for the motor current. It doesn’t mention it’s internally protected. I have enough dead time to ir2101 sure gates do not short.

At first it happened twice on the driver ir2101 away from 48v connector.

Any attached file to the reply which will help to support your inquiry is highly appreciated. I’m using 3x of these circuits to drive a BLDC motor with 0. Where do you mean that I should place the low-ESR caps? I ir2101 added a single 47uF 63v cap in the ir2101 at the top. In order ir2101 optimize your browsing experience Infineon uses cookies. I have seen schematics using resistors.

This can manifest ir2101 in two ways:.

Ir2101 current circuit that fails does not have the diodes over the resistor to further delay turn on. Where have you seen resistors ofit ir2101 be that they were 3.

Also on my test circuit the rightmost ir2101 voltage divider resistors are not mounted. This ir2101 to work. Some conflicting advice here.

IR – Infineon Technologies

My tests only confirm that higher resistance increases turn on time. The circuit works up to a certain current through the mosfet but then the ir2101 mysteriously fails and pulls both mosfets high generating a short ir2101 on the output.

I was able to spin up the motor to speeds at which ir2101 draws 5A and do instant spinups from zero to full throttle as well as instant stops without ir2101 anything so far.
