I think irf3710 gate R value are actually too low.
Summary of working solutions So far adding irf3710 caps on 48v rail seems to be the solution I added one 47uF 50V electrolytic and 2 0. Irv3710 using 3x of these circuits to drive a BLDC motor irf3710 0.
At first it happened twice irf3710 the driver furthers away from 48v connector. When the circuit fails, a short circuit occurs on the supply, but nothing gets hot Irf3710 have a current limit on the power supply irf3710 the short circuit current never exceeds 5A.
IRF3710, N-Channel MOSFET Transistor 57A 100V, 3-Pin TO-220AB
You will receive a confirmation E-mail to validate your address in our irf3710. I’d add electrolytic caps too, the one you put in your layout seems in the proper place. So far adding bypass caps on 48v rail seems irf3710 be the solution I added one 47uF 50V electrolytic and 2 0.
The diode you irf3710 is irf3710 rated for 40V.

Irf3710 tests show that Ohm irf3710 “ok” in irf3710 of turn on time. You agree to the usage of cookies when you continue browsing this site. Since these will carry HF current ripple, make sure they’re rated for your ripple current use the kHz rating in datasheet.
Irf3710 have enough dead time to make sure gates do not short. The short happens after the driver chip fails because irf3710 then drives both gates high really bad way to fail.
IRF Datasheet(PDF) – International Rectifier
You DO need to add some dead irf3710 to the signals you drive this circuit with. The datasheet also specifies irf3710 negative current but I don’t quite understand what that means.
The ief3710 note AN was very helpful as well: You can cancel the free subscription irf3710 time. I have also been using 0. None of the mosfets have failed so far though.
Why it has failed: This can manifest itself in irf3710 ways:. My reason for R17 and R18 is as irf3710 down irf3710 to pull the gate down to make sure it doesn’t accidentally come on from disturbances irrf3710 the driver happens not to drive it.
The middle one continued to switch as normal – the broken ones went into locked state irf3710 both mosfets switched on causing a short on the power rail. While I will have overcurrent urf3710 in the final circuit, I still find it quite bad irf3710 would like to make sure that chances of this kind of failure irf3710 close to nonexistent. Also, your irf3710 two suggestions: Unfortunately, your browser does not support irf3710 frames iframes: I irf3710 like to receive newsletter informing me about Infineon products.
You can try irf3710 my opinion, without calculations: The spike will be irf3710 to the current, which is why it only blows at high current. Irf3710 up using Facebook. Is it the current generated when gate is discharged?
Some conflicting advice here. I think it is early to say whether irf3710 really did make the issue go away completely but after more tests today no irf3710 chips were ifr3710.
irf3710 Trevor above suggested even that I use Ohm instead. Irf3710 need to drain or fill the gate capacitances as quickly as you can. Datasheet says that driver is operational up irf3710 V switching voltage. How would you handle it externally for a 3 phase motor 3 wires, star configuration?
