  • Publication number: 20220173737
    Abstract: A semiconductor device is provided; the semiconductor device includes unipolar transistors. A steady-state current does not flow in the semiconductor device. The semiconductor device uses a high-level potential and a low-level potential to express a high level and a low level, respectively. The semiconductor device includes unipolar transistors, a capacitor, first and second input terminals, and an output terminal. To the second input terminal, a signal is input whose logic is inverted from the logic of a signal input to the first input terminal. The semiconductor device has a circuit structure called bootstrap in which two unipolar transistors are connected in series between the high-level potential and the low-level potential and a capacitor is provided between an output terminal and a gate of one of the two transistors. A delay is caused between the gate of the transistor and the signal output from the output terminal, whereby the bootstrap can be certainly performed.

  • Publication number: 20220077705
    Abstract: A secondary battery deteriorates due to repeated charging and discharging, which leads to a decrease in a battery voltage and a battery capacity. The lifetime of a secondary battery is prolonged by preventing charging at an excessive charging value that would be caused by deterioration of the secondary battery. By performing charge control in consideration of the degree of deterioration of a secondary battery, a longer lifetime of a secondary battery can be achieved. In charging a secondary battery, a charge control circuit controls a current value to a preset value, and a charging current control circuit (specifically a circuit including an error amplifier) included in a protection circuit determines a current value supplied to the secondary battery. That is, the current value supplied to the secondary battery is controlled by both the charge control circuit and the charging current control circuit that is a part of the protection circuit.
