Hello everyone. I am going to this forum to see if anyone can help me.
I have purchased two batches of the integrated LTC6811 from Chinese resellers. I attach a photo.
The chips above work perfectly. However on the same hardware and with the same microcontroller firmware the ones below don't work.
Are they fakes?
Can there be differences in performance depending on the serial number? The datasheet does not indicate the meaning of the serial numbers on the integrated ones.
