Sales Briefcase
  • 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.
