STEVAL-ISB008V1

Standalone USB Li-Ion battery charger demonstration board based on the STw4102 and STM32F103C6
  • NRND NRND

The STEVAL-ISB008V1 demonstration board is based on the STw4102 battery charger device and the STM32F103C6 microcontroller. The board is designed as a complete standalone battery charger, and includes a gas gauge to monitor battery capacity using five LEDs to represent different capacity levels. Two status LEDs indicate battery charging, discharging and some fault conditions.

By default, the firmware programmed in the demonstration board considers a battery capacity of 1200 mAh. This maximum capacity value is used to identify the percentage of available battery capacity, which is shown using the 5 LEDs.

The demonstration board firmware allows the user to vary the maximum capacity up to 2100 mAh, in steps of 300 mAH.

The STM32F103C6 microcontroller is used to control and monitor the STw4102 battery charger device.

All communication between the STw4102 and the STM32F103C6 is done through an I2C interface.

The STEVAL- ISB008V1 is equipped with both a USB and a DC adapter connector.

The board can supply a maximum battery charging current of 400 mA for a USB port, extending to 800 mA for a DC adapter.
