There are a few places in the bq78350-R1 TRD that refer to FET tests. I can’t find anyplace where these tests are explained. Do these status bits indicate that the FETs were turned on with a ManufacturerAccess? If not, what do they indicate?
17.2.41 ManufacturerAccess() 0x0057 ManufacturingStatus
DSG_TEST (Bit 2): Discharge FET Test
1 = Discharge FET test activated
0 = Disabled
CHG_TEST (Bit 1): Charge FET Test
1 = Charge FET test activated
0 = Disabled
PCHG_TEST (Bit 0): Precharge FET Test
1 = Precharge FET test activated
0 = Disabled
17.24 0x16 BatteryStatus()
DSG (Bit 6): Charge FET Test
1 = Battery is discharging or at rest.
0 = Battery is charging.
