I have a product use the INA199A1DCKR to check the current. after the PCBA done and the hardware QC pass (contain the current check), it work normal, but when it ship it to our client, there are 2pcs PCBA has the issue, it cause by the INA199A1, the IN- to GND forward voltage is 0.144 V,and the IN+ to GND forward voltage is 0.7 V. I think it may damaged when it transporting or assembling, may caused by ESD? The schematic is according to the ddatasheet.,the battery is 7.4V. Is it has some problem on my designed? I hope you can give me some feedback, thank!
