Description

The STBCFG01 is a switching battery charger

integrating the necessary functions to charge

single cell Li-Ion batteries, monitor the battery

charge and generate 5 V to supply USB OTG bus

powered devices.

The IC also integrates the LDO regulator to

support system boot in dead battery conditions.

The battery charger features a smart input

current limit: the maximum input current can be

selected through I²C and if the input voltage

drops below a programmable threshold, the input

current is reduced even if the selected maximum

current limit has not been reached yet. The

dynamic input current limit can be disabled.

An automatic input pre-bias load makes the

device suitable for applications using voltage

sources with a minimum external load for the

right regulation.

The STBCFG01 also integrates a voltage mode

fuel gauge to provide the state of charge

evaluation without the current sensing resistor.
