Part Number:BQ40Z50
Hello,
We are currently using the BQ40z50 chipset in one of our smart battery packs, and are developing several new packs which will use that same chipset.
We built a labview based test system to electrically test and verify communications and certain data fields in our smart batteries. We are using a national instruments usb8451 for the system communications to the battery pack.
We have encountered a problem with this setup that we cannot figure out. We test the 20z75 and the 34z100 without any problems.
When we test the packs using the 40z50, it causes the usb8451 to "lock" up and the labview test environment to crash. These crashes will happen about every 3 to 4 packs we try to communicate with.
We are at a loss to why this is occurring and need help solving it.
