  • Voltage detection circuit
    Patent number: 9671469
    Abstract: A voltage detection circuit for a secondary battery. A secondary battery is composed of a plurality of battery blocks (B1) to (B3), and is connected to a flying capacitor (C1) via input side sampling switches (SW1) to (SW3). The flying capacitor (C1) is connected to a differential amplifier circuit (10) via output side sampling switches (SWa) and (SWb). A feedback capacitor (C2) is connected to an inverting input terminal of the differential amplifier circuit (10) to form an integrator circuit, which reduces the capacitance of the flying capacitor (C1).
    Type: Grant
