IT
The IT bit configures the bq2085âV1P2 to use its internal temperature sensor.
0 bq2085âV1P2 requires an external thermistor.
1 bq2085âV1P2 uses its internal temperature sensor.
AC
The AC bit enables the SAFE output to function based on the AFE integrity check.
0 SAFE is not activated based on the AFE integrity check.
1 SAFE activated based on the AFE integrity check.
DS
The DS bit programs the bq2085âV1P2 to enter sleep mode on SMBus inactivity.
0 bq2085âV1P2 enters sleep mode when the SMBus is low for 2 s.
1 bq2085âV1P2 does not enter sleep mode.
OT
The OT bit programs the bq2085âV1P2 to turn off the discharge FET when the bq2085âV1P2 detects an
overtemperature condition. Charge FET is always turned off in overtemperature conditions.
0 bq2085âV1P2 does not turn off the discharge FET on overtemperature.
1 bq2085âV1P2 turns off the discharge FET on overtemperature.
ECLED
The ECLED bit programs the LED activity during charging (DSG bit = 0).
0 The LEDs are not enabled during charging.
1 The LEDs are enabled during charging.
PHG
The PHG bit configures the bq2085âV1P2 to control a precharge FET.
0 The bq2085âV1P2 does not control a precharge FET.
1 The bq2085âV1P2 may turn on or off a precharge FET according to the programmed precharge
conditions.
VOD
The VOD bit enables a 1-second time delay on the charge and discharge FET control.
0 No delay
1 1-second delay
