IT
The IT bit configures the bq2083−V1P2 to use its internal temperature sensor.
0 bq2083−V1P2 requires an external thermistor.
1 bq2083−V1P2 uses its internal temperature sensor.
AC
The AC bit enables the SAFE output to function based on the AFE integrity check.
0 SAFE not activated based on the AFE integrity check.
1 SAFE activated based on the AFE integrity check.
DS
The DS bit programs the bq2083−V1P2 to enter sleep mode on SMBus inactivity.
0 bq2083−V1P2 enters sleep mode when the SMBus is low for 2 s.
1 bq2083−V1P2 does not enter sleep mode.
OT
The OT bit programs the bq2083−V1P2 to turn off the discharge FET when the bq2083−V1P2 detects an
overtemperature condition. Charge FET is always turned off in overtemperature conditions.
0 bq2083−V1P2 does not turn off the discharge FET on overtemperature.
1 bq2083−V1P2 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 bq2083−V1P2 to control a precharge FET.
0 The bq2083−V1P2 does not control a precharge FET.
1 The bq2083−V1P2 may turn on or off a precharge FET according to the programmed precharge
conditions.
