BATTERY CHARGER

摘要

A battery charger includes an input supply terminal configured to receive a supply signal and a battery terminal configured to be connected to a battery. A supply switching circuit is arranged between the battery terminal and the input supply terminal. A control device generates a control signal to control operation of the supply switching circuit. A fuel gauge device provide a digital estimation of a voltage signal across the battery. A correction device modifies the control signal in response to the digital estimation of the voltage signal across the battery if that digital estimation is outside of a value range between two thresholds.

1. A battery charger, comprising:
an input supply terminal configured to receive a supply signal, a battery terminal configured to be connected to a battery, a supply switching circuit arranged in an electrical path between the battery terminal and the input supply terminal, a control device configured to generate a control signal to control operation of the supply switching circuit, a fuel gauge device configured to provide a digital estimation of a voltage signal across the battery, a correction device configured to modify said control signal generated by the control device if said digital estimation of the voltage signal across the battery is out of a value range between a first threshold and a second threshold, wherein the first threshold is lower than the second threshold.
