This board is for evaluating the BD71631QWZ, a linear battery charger IC.
The BD71631QWZ accepts a power supply in a range from 2.9 V to 5.5 V, and generates a battery-charging voltage from 2.0 V to 4.7 V, which can be set using external resistors. The charging current and termination current can also be set with external resistors. The BD71631QWZ is compatible with not only single-cell lithium-ion batteries, but also all solid, semi-solid and other new rechargeable battery types that call for low-voltage charging.
The board’s operation is safeguarded by various protection functions implemented in the BD71631QWZ.
