Patent ID: 11947372
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Control (Instruments)
Classification: CPC G  H | IPC G

Claim 11:
12. A device, comprising:
a voltage regulator circuit comprising a plurality of first transistors;
a power switch circuit coupled in parallel with the plurality of first transistors,
wherein when the power switch circuit is turned off in a first operation mode, the voltage regulator circuit is configured to be turned on to generate an output signal to an output terminal, wherein the output signal has an output voltage of a first voltage level equal to half of a supply voltage, and
the power switch circuit is configured to be turned on in a second operation mode to pull up the output voltage from the first voltage level to the supply voltage; and
a detection circuit configured to generate, in response to the output voltage, a plurality of first control signals to turn on the power switch circuit.
