Abstract
The utility model discloses an input voltage regulation circuit, device and system, and the circuit is characterized in that when a voltage regulation module in the circuit receives a first voltage regulation signal, voltage division is carried out on an input signal through a first voltage division loop, and a first voltage division signal obtained after voltage division is output to a to-be-operated device; the voltage comparison module transmits a second voltage regulation signal to the voltage regulation module when detecting that the voltage of the input signal is smaller than the first voltage; and when the voltage regulation module receives the second voltage regulation signal, the input signal is subjected to voltage division through a second voltage division loop, and the second voltage regulation signal obtained after voltage division is output to the to-be-operated device. According to the invention, the voltage of an input signal can be detected, and when the voltage is greater than the first voltage, voltage division is carried out through the first voltage division loop; and when the voltage is smaller than the first voltage, a second voltage division loop in the voltage regulation module is used for voltage division, so that input voltages with different voltage values can be adapted, and the voltage detection range of the to-be-operated device is widened.
