SHUNT CIRCUIT, CHARGING SYSTEM AND INTEGRATED CIRCUIT |
| 摘要 |
A shunt circuit includes: a shunt resistor; a transistor connected in parallel to a storage element via the shunt resistor; a first OP amplifier configured to compare a battery voltage supplied to the storage element with a detection voltage; and a second OP amplifier configured to shunt a shunt current from a charging current supplied from a charging unit when the battery voltage reaches the detection voltage. The detection voltage is increased step by step, and the shunt current is increased whenever the battery voltage reaches the detection voltage. |

1. A shunt circuit comprising:
a shunt resistor; a transistor connected in parallel to a storage element via the shunt resistor; a first OP amplifier configured to compare a battery voltage supplied to the storage element with a detection voltage; and a second OP amplifier configured to drive the transistor to shunt a shunt current from a charging current supplied from a charging unit when the battery voltage reaches the detection voltage, wherein the detection voltage is increased step by step, and the shunt current is increased whenever the battery voltage reaches the detection voltage.
