Title:
CIRCUIT HAVING POWER FAILURE DETECTION AND POWER SUPPLY HOLDING FUNCTIONS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/087737
Kind Code:
A1
Abstract:
A circuit having power failure detection and power supply holding functions, and an electronic device. The circuit having power failure detection and power supply holding functions comprises: a power output end connected to an electric load; an energy storage circuit (10); a power supply holding control circuit (20) having an input end connected to an output end of the energy storage circuit (10) and an output end connected to the power output end; and an energy storage voltage detection circuit (30) having a detection end connected to the output end of the energy storage circuit (10) and an output end connected to a controlled end of the power supply holding control circuit (20), and used for detecting an output voltage of the energy storage circuit (10), and controlling, when the output voltage of the energy storage circuit (10) is less than a first preset voltage, the power supply holding control circuit (20) to disconnect the electric connection between the energy storage circuit (10) and the power output end, so that the energy storage circuit (10) stops supplying power to the electric load.
