Methods, devices and circuits are provided for power-on-reset circuits with low static power consumption. One such circuit includes a detector that draws current from a supply voltage. The detector detects that the supply voltage has exceeded a trip-point voltage level and then disables current draw from the detector. The detector responds to an enable signal by enabling current draw from the detector. A pulse generator generates a reset signal in response the supply voltage transitioning from a voltage below the trip point voltage level to above the trip point voltage level. A monitor detects that the supply voltage has dropped and provides, in response thereto, the enable signal to the detector to enable current draw from the portion of the detector.
