Reply to "Weak or NO DCS signal from TIU"

I came up with a design with Schottky diodes and a 1500W TVS to attempt to mitigate this issue right at the chip. It clearly hasn't received wide field testing, I can only say one TIU with these installed hasn't eaten any 'ACT244 chips. This was discussed in another thread, but didn't receive enough interest to invest in a production run.

The module is glued to the top of the 72ACT244 chps and wired to the four pins directly in line with the module connections. I just stuck them down with Aleene's Tacky Glue, the glue is just to keep them in place until you solder the wires. I didn't think to take pictures of the TIU when they were installed...
