Abstract
A voltage supervisor includes a first transistor coupled between a first supply voltage and a second supply voltage. The voltage supervisor includes a second transistor coupled between the first supply voltage and the second supply voltage. The voltage supervisor is configured to provide a first current proportional to a difference in gate-to-source voltages of the first transistor and the second transistor. The voltage supervisor is also configured to provide a second current proportional to a difference in the first supply voltage and the difference in gate-to-source voltages of the first transistor and the second transistor. The voltage supervisor is configured to compare the first current to the second current to determine a voltage value that changes a state responsive to the first supply voltage crossing a threshold.
