Other Parts Discussed in Thread: BQ76940
Hi;
I am working on Bq76940 referance design Tıda-00255 and I choose the sense resisitor 1m ohm as the same as on the EVM but there is a strange issue that I met.When the BATT- pin and GND connected with net_tıe the voltages across the cells are observed truely but the current wrongly on the interface that BQ769X0 software for example it is 4A but on interface it is 6.9 A ; but on the other hand when BATT- and GND pins are not connected to each other ;the current seems true but this time the voltage measured wrongly by IC especially the first and the last cells.
Thanks.
