Gate Driver ICs Forum Discussions
I'm trying to Switch battery Power which has 19.2 ~ 21.6V / pK 400A / nominal Max 200A
And trying to use 12 X IRF7480 with AUIR3241S driver
Is my configuration is OK ?
I upload my schematic, it wil be very appreciate If you review my schematic
I'm not able to download the Pspice model for IR2110 from the website, " the web site encountered an error."
Anyone can help?
I received a component with following information written on it: A2085 / A441P / IR / C / STX3. I suppose it was manufactured in the 41st week of 2004, isn'it ?
Is the die version of this device the same as the present production?
Thanks a lot beforehand.
1. Digikey discribes this ic as 'IC IGBT DVR 1200V DSO8' however there is no mention of it being able to drive an IGBT in the datasheet. It only speaks to driving MOSFETs. We have already taken into consideration the correct voltages for switching but just to be sure, is it possible for this ic to drive IGBTs?
2. We are using transformer technology in our design, would it be alright to run wires under this gate driver. Would there be a chance of causing any interference if this is done?Show Less
where it looked like high side UVLO (the high side just stopped working) even though the low side continued working. I spent ages scoping the high side
and changing components in the boost circuit to no avail. Eventually in desperation I grounded the previously floating Sd pin and the fault went away!
I should emphasize this was a swap from an IRS2110 to an IRS2113 in the same pcb in a previously working circuit. Both date codes concerned 713P
so it seems maybe I was lucky before or the 2113 is more sensitive, in either case I would never rely on the internal pulldowns again.

I want to ask whether AUIR3240S can be applied to back-to back FET configuration as AUIR3241S.
I don't see back-to-back configuration in AUIR3240S .
any body can suggest proper gate driver IC for back-to-back connection ?

I am using IR21814S for LLC gate driver, and I need to limit the minimum duty of PWM signal. Could you help address the minimum HI/LI on pulse requirement for IR21814S? Thank you. Show Less
I have attached the circuit. I'm trying to drive a coolgan HEMT (IGOT60R070D1) with driver - 1EDF5673F.
PROBLEM - 1) When I tested the driver alone (without connecting the switch and the power circuit), the driver always shows -8V as output at the "gate to source terminal" irrespective of what I give at the PWM input pin.
PROBLEM - 2) When I soldered the gan switch, the SK pin of the switch draws considerably high current (more than 200-300mA). (drive still gives -8V between G-SK of device)
Can anyone help with this problem? What am I missing?
PS: I have soldered two boards with new components to confirm the above symptoms. So i'm sure its not the soldering issue or damaged ICs. Show Less
We have used TLE9183 in our design,now I am writing DFEMA,I am confused on what will happen to this IC when two pins of this driver IC short to each other or one pin open. Could you provide me some documents which have that contents? such as safety manual? or something like that?Show Less
