Product overview
Description
The STEVAL-ISB002V1 is a universal battery charger (UBC) demonstration board based on the ST72F324L microcontroller.
The charger used in this demonstration board uses a modified form of a non-inverting buck-boost converter to support the charging voltage requirement for single-cell Li-ion batteries.
The board includes a 3.3 V power supply generated from a KF33 regulator and a precision reference voltage generated from the TL1431, bearing in mind the accuracy requirement for charging. A status LED is used to show the charging status.
This demonstration board is capable of charging single cell Li-ion batteries with in-built NTC or a 2-cell NiMH battery from a 5 V supply. The firmware is easily upgradeable and can be modified for other ST7 microcontrollers depending on application requirements.
