Abstract:
A temperature condition indicator in an integrated circuit comprising:a first current source that sources a first current in response to a temperature of the integrated circuit, wherein the first current increases in response to an increase in the temperature of the integrated circuit; a second current source that sources a second current in response to the temperature of the integrated circuit, wherein the second current decreases in response to an increase in the temperature of the integrated circuit; a programmable temperature detector, coupled to the first and second current sources, wherein the programmable temperature detector generates a first voltage signal in response to the first current and a plurality of switches and generates a second voltage signal in response to the second current and the plurality of switches, wherein the plurality of switches are set external to the integrated circuit; and a comparator, coupled to the programmable temperature detector, wherein the comparator compares the first and second voltage signals to provide a temperature state of the integrated circuit.
