JeffLowe Posted April 17, 2019 Share Posted April 17, 2019 I note that the 460EX uses the same LBA716 Dual Single-Pole OptoMOS relay as the ACC24E3. Does it have a similar design problem with an improperly sized driver gate or the excessive current due to a undersized resistor? We have had some faults with this relay.

steve.milici Posted April 23, 2019 Share Posted April 23, 2019 There have been no reports of issues with the WD circuit on this CPU. It has been in production since 2008. Link to comment Share on other sites More sharing options...
JeffLowe Posted April 23, 2019 Author Share Posted April 23, 2019 There have been no reports of issues with the WD circuit on this CPU. It has been in production since 2008. Yet again, there were no reported problems with the ACC24E3 amp enable circuit either, but the ECO process on that one is a major headache for us right now. The CPU uses the same opto relay and I just was hoping someone could look at the schematic and verify if the same driver nand gate was used and/or the same pullup. I am just hoping we can be proactive. Link to comment Share on other sites More sharing options...
steve.milici Posted April 23, 2019 Share Posted April 23, 2019 This circuit has been reviewed. It has a much better pre-driver and properly sized pull-up resistors. We do not feel that there would be any issues as in the ACC-24E3. Link to comment Share on other sites More sharing options...
