Abstract: A circuit for detecting an input voltage includes a voltage-to-current converter and a current comparator. The voltage-to-current converter is operable for generating a monitoring current that varies in accordance with the input voltage. The current comparator coupled to the voltage-to-current converter is operable for comparing the monitoring current to a threshold current proportional to the temperature of the circuit, and for generating a detection signal indicating a condition of the input voltage based on a result of the comparison.
