Title:
LOW POWER CONSUMPTION CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/228052
Kind Code:
A1
Abstract:
A low power consumption circuit and an electronic device. The low power consumption circuit comprises a trigger unit (110), a delay unit (120) and a first switch unit (Q1). The first switch unit (Q1) comprises a first controlled terminal, a first power input terminal and a first power output terminal. The first power input terminal is configured to be connected to a power supply, and the first power output terminal is configured to be connected to a load. An input terminal of the delay unit (120) is connected to the trigger unit (110), and an output terminal of the delay unit (120) is connected to the first controlled terminal. The circuit further comprises a second switch unit (Q2) and a controller (MCU), the second switch unit (Q2) comprising a second controlled terminal, a second power input terminal and a second power output terminal. The first controlled terminal is further connected to the second power input terminal, and the second power output terminal is connected to a low level. The controller (MCU) is configured to monitor the duration of the trigger unit (110) being triggered, and control, by means of the second controlled terminal, the second power input terminal and the second power output terminal to be turned on or off according to the triggered duration. By means of the invention, the timing for controlling a power supply to supply power to a load can be accurately determined, so as to avoid an erroneous control operation
