The NBM5100A/B evaluation board enables the evaluation of Nexperia battery booster products, which are integrated circuits intended to expand the lifetime and current capability of primary batteries (such as coin cell or Lithium Thionyl batteries).
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.
