Abstract
There is provided a voltage supply circuit, in which a signal output end of a power management integrated circuit, a signal input end of a transmission branch, and a signal input end of a voltage reduction branch are coupled to a first node; a signal output end of transmission branch and a signal output end of the voltage reduction branch are coupled to a second node; the power management integrated circuit supplies an initial voltage to the first node; the transmission branch is coupled to a control signal terminal, and switch between a conducting state and a cutoff state in response to control of a control signal, and write the initial voltage into the second node in the conducting state; and the voltage reduction branch performs voltage reduction on the initial voltage at the first node to obtain a reduced voltage to be written into the second node.
