The invention provides a low-power-consumption low-
voltage detector, which relates to the technical field of detectors and comprises a detection
branch, a bias
branch and an output shaping module, the first end of the detection
branch is connected with
power supply voltage, the second end is connected with the bias branch, and the detection branch is used for outputting an overturning
signal when the
power supply voltage reaches set detection
voltage; the bias branch is used for providing stable bias
voltage for the detection branch and has a temperature compensation function; and the output shaping module is connected with the output end of the detection branch and is used for shaping the overturning
signal and then outputting a detection
signal. In the mode, ultralow detection voltage, ultralow
power consumption, temperature stability, high process angle robustness and small
chip area are realized, and the detection voltage is programmable.
