Zombieverter: MIC4422YM v.s. FAN3122

[Sjanders]

Hi,

So, last week I received my Zombie! Yay, let the fun start

Opening the package and checking for completeness I found that the shipment included 3x MIC4422YM and 1x NCV8461 mosfet drivers. Based on the BOM and the Zombieverter wiki I expected to receive 3x FAN3122 and 1x NCV8461 drivers.

Based on the number of 4422YM drivers I assume they should populate position IC27, IC28 and IC29.

I've compared both drivers, they both seem to have the same functionality, the main difference between them seems that the MIC4422YM has a higher max. output current: 9A v.s. 4A.

I assume the MIC4422YM drivers are replacements for the FAN3122 driver, but I'd like to know for sure since I can't find any post on this. Could someone verify that my assumption is right?

Many thanks!

Yes that is correct. The MIC4422YM are replacements for the FAN3122 as the latter seems to be out of stock in most places at the time of writing.

Added the alternative part number to the wiki page, https://openinverter.org/wiki/ZombieVerter_VCU#Hardware

Thank you very much! Let's get soldering then

Hi Sjanders,

Like you I have recently received my Zombie, with the same 4 IC’s that need to be soldered onto the board (IC12 & Ic’s27-29). I have been looking for confirmation of which parts go where, and your Query, and Damien’s reply have cleared that up - so many thanks to both of you. I also have a query regarding the wifi module that I hope you can help me with. Do you know the correct orientation of that module? In one of Greg from “ Good Enuff Garage” videos it appears that he has his situated with the wifi module on the top side. Do you knowifthat is correct? Thanks in advance, and good luck with your build!

Wifi goes on the top of the board like the other components.

Hi Iceman,

Did you manage to get the Zombie operational? I have mounted the WIFI module, like Tom pointed out and according Gregski's video's, on top of the board. The WIFI antenna face the right side of the board when viewing from the connector pins. Up till now all steps I'm taking in the process work just fine!

Good luck!

Hi Sjanders - out of interest - how far along are you with your project? I am trying to test my zombie with my leaf stack out of th3 car, but am having a few issues. I cant seem to get my ISA shunt reading correctly. I had issues getting it initialised at first, but I think I got that sorted, but it is still not showing any volts or amps. The other issue I have is when I supply the ignition signal to the zombie it receives it OK, but does not energise the relay to power up the inverter and pdm, which is what the wiki says should happen. But if i also give it a momentary start signal, the relay energises and powers up the inverter and pdm, and the precharge and negative contactors close ok, but after 5 seconds I get a precharge fail message, and the precharge contactor drops out, because the shunt is not reading a voltage( interestingly the negative contactor does not drop out). If I drop the udcsw setpoint to 0 volts and run the sequence again, it also powers up the main contactor, and the Zombie goes into Run mode. So I just need to get my shunt working properly. I have read a couple of different methods on here for initialising the shunt, so I will give the method I haven’t tried yet a go and see if that is any better

Hi Iceman,

I think you should set up a new thread to explain your issues. Likely the knowledgeable people here can help you out.

Off topic: Unfortunately, at this point I'm not able to help you out as you are like miles ahead on my progress . Tomorrow I receive my BMW 12 kW pack, first I will tear in down and test the modules and the S-BOX. When all is fine next steps will follow.

Good luck with your next method, hopefully it works out as planned!

Cheers!

Hi Sjanders - good call - I will start a dedicated thread - thanks
