More Information
Summary:A voltage monitoring apparatus and a voltage detection circuit thereof are provided. The voltage detection circuit includes a first part circuit and a second part circuit. The first part circuit includes a first load and a first active load. The first active load generates a first current to flow through the first load according to a first bias voltage. The second part circuit includes a second load and a second active load. The second active load receives a second current flowing through the second load, and generates a second bias voltage correspondingly, where the first current equals to the second current. Wherein, a detection voltage provided by the first part circuit is equal to a voltage difference between positive and negative ends of the battery cell.
