A device for providing a reset signal to one or more sequential logic circuits in an electronic system responsive to a supply voltage condition includes a first voltage detector circuit to generate a first pulse after the supply voltage rises to a first threshold voltage level. The device further includes a second voltage detector circuit to generate a second pulse after the supply voltage falls below a second threshold voltage level. The device additionally includes a latch circuit to store a first value based on the first pulse after the supply voltage rises to the first threshold voltage level, disable the first voltage detector circuit after storing the first value, reset to store a second value based on the second pulse after the supply voltage falls below the second threshold voltage level, and to disable the second voltage detector circuit after the resetting.
