  • Voltage detection circuit, power supply system and chip
    Patent number: 11604216
    Abstract: A voltage detection circuit, a power supply system and a chip are provided. The voltage detection circuit includes: a first step-down sub-circuit, a second step-down sub-circuit and a first voltage-stabilizing sub-circuit; wherein the first step-down sub-circuit has one end connected to one end of the second step-down sub-circuit in series; the first step-down sub-circuit has another end connected to a first port of the voltage detection circuit; and the second step-down sub-circuit has another end connected to a second port of the voltage detection circuit; and wherein the first voltage-stabilizing sub-circuit has one end connected to a third port of the voltage detection circuit and has another end connected to the second port, where the first voltage-stabilizing sub-circuit is turned on when the third port has a voltage higher than the second port and stabilized when the third port has a voltage lower than the second port.
