  • Protecting circuit and integrated circuit
    Patent number: 10498137
    Abstract: A protecting circuit includes a discharge switch, a trigger circuit, and a shunt circuit. The discharge switch is connected between a first terminal and a second terminal. The trigger circuit is connected to the discharge switch and comprises load devices, connected in series between the first terminal and the second terminal, and a first node between a first one and a second one of the load devices. The shunt circuit is connected to the trigger circuit at the first node, where the shunt circuit comprises a shunt switch and a shunt pathway that is connected between the first node and the shunt switch.

  • Protecting circuit and integrated circuit
    Patent number: 9871374
    Abstract: A protecting circuit includes: a discharge switch configured to connect to a first terminal and a second terminal; a trigger circuit comprising load devices configured to be connected in series between the first terminal and the second terminal, each of the load devices being configured to consume power; and a shunt circuit comprising, between the trigger circuit and the first terminal or the second terminal, at least one shunt pathway configured to be capable of bypassing at least one of the load devices. The trigger circuit is configured to turn on the discharge switch when a voltage between the first terminal and the second terminal is higher than a first voltage value, and the shunt circuit is configured to electrically connect the shunt pathway when the voltage is higher than a second voltage value that is greater than the first voltage value.
