Product overview
概要
The STEVAL-ISB033V1 is an evaluation board to test the first-of-its-kind STBCFG01 switch mode battery charger for single cell Li-Ion batteries, which integrates a highly accurate voltage mode fuel gauge to monitor a battery's state of charge. The device also provides a 5 V output to supply USB OTG (on-the-go) bus-powered devices in addition to an LDO linear voltage regulator to support system boot in dead battery conditions.
The STBCFG01 uses accurate measurements of the battery voltage which allows the estimation of the battery's state-of-charge (SOC) without a current-sensing resistor. The switching charger works together with the fuel gauge to simplify monitoring features and to save current consumption when the device is not charging. The battery charger features a smart input current limit; the maximum input current can be selected through the I²C interface, and if the input voltage drops below a programmable threshold, even if the selected maximum current limit current has not been reached yet the dynamic input current limit function is activated, preventing the input current from increasing further. The dynamic input current limit function can be disabled, if necessary. An automatic input pre-bias load makes the device suitable for applications using voltage sources requiring a minimum external load for correct regulation.
