Figure 5: DICL activation

When a valid input source is connected to DCIN, DICL is enabled only if the input voltage is

status of DICL function reading DICL status bit. Once DICL is enabled it can be disabled

through DICL_en bit.

5.1.3

Automatic recharge

When the charging cycle is over, the device keeps monitoring the battery voltage: if the

charging cycle starts to keep the battery at maximum capacity. The automatic recharge

function can be disabled through I²C.

5.1.4

Battery detection

The battery charger IC features a battery detection function to check if a battery is inserted

before starting the charging cycle and to make sure that charging termination is not

triggered because of a battery disconnection. If the battery is not detected when the input

voltage is valid, the device keeps running the detection sequence until a battery is inserted.

The battery detection result is reported by DET_ok bit. If the battery detection function or

RID comparator detects a battery disconnection, BAT_Fail interrupt is generated. See the

battery detection algorithm flowchart for more details.
