IRAM256-2067A2 Obsolete and out of stock

[maxschommer]

IRAM256-2067A2 is obsolete and out of stock everywhere I looked.

[crinq]

Yes, Infineon discontinued it after they bought IR.
New design is in the pipeline.

IRAM256-1567A2 or IRAM256-1067A2 can be used as replacement, but they only have 15 and 10A, but thats plenty for most servos.
they are still available at mouser.

Have you chosen a new part for the next revision yet? I'd like to get some boards made soon so would like to start gathering components.
Many thanks for this project!

[rene-dev]

the next revision is far from complete, dont bother stocking parts. Make v4 if you cant wait.

[rene-dev]

All A2 models seem to be out of stock now. The A models can be bodged in:

Any progress with new revision?

[crinq]

yes, but not ready yet

can we replace IRAM256-2067A2 with ON semiconductors- STK551U3A2A-E ?

No this does not work with 3 low side shunts (connected emitters of the lower igbts).
The next STMBL version has a discrete 3 PH bridge with TO220, but the design is not ready yet.

[meet-gopani]

okay, thank you!
STK554U392A-E: this is 15A version and this works with 3 low side shunts

will it work?

I know I feel like a total nag. I was going to build one of these, the bought a full CNC instead....but it turns out that machine can't get "Polygonal turning" (I want it for gear hobbing) so I'm going to add a spindle I can synchronize. I was planning on the full 2Kw. I may see if I can beg for one of the older chips. I'm not requiring this....now....as I've got some other design and building to do of the mechanical parts. Any hints as to when it will be out? Any beta's? as long as its not going to catch on fire, I'm game :)

I have a source, they got 20 units of the IRAM256-2067A2 in Stock left, but these costs 44,06€ per piece. If you think it is worth it i can order these IBGT Modules. I am from Germany (Berlin).

[awigen]

I'd like to order three!
