Abstract
A circuit includes a temperature-sensitive voltage divider. The temperature-sensitive voltage divider includes a temperature-sensitive resistor and a second resistor having a first terminal coupled to a first terminal of the temperature-sensitive resistor. A temperature signal is generated at a first node coupled to the first terminal of the temperature-sensitive resistor. Detection logic is coupled to the first node to generate a detection signal responsive to the temperature signal.
