Hi Expert,
My customer is using TPS40400 on one project. During the program burning procedure on the product line, they found one module couldn't import the input UVLO register value successfully. They checked the operation method and found this was caused by the power on and power off sequence. After that, all of the module couldn't import the input UVLO value successfully even they correct the power sequence. Could you check if the below process is correct for burning the program during production?
1).Power Off--------2).put the module on the bench slot-------3). Power on-------4). import the program--------5). the screen shows the program imported successfully-------6). Power Off--------7). Pick out the module from the bench slot--------8). Put another module on the bench slot and repeat step 1 to step 7
