Abstract
A system and method is disclosed that provides a thermal shutdown circuit that generates a plurality of temperature warning flag signals. Each temperature warning flag signal represents a different temperature. The thermal shutdown circuit comprises a plurality of inverter circuits in which each inverter circuit has a different temperature turn-on threshold. A temperature to binary code converter receives the temperature warning flag signals from the inverter circuits and generates a plurality of binary coded signals that represent a temperature that is detected by the thermal shutdown circuit. A host controller unit uses the temperature information from the binary coded signals to shut down subsystems in advance of an abrupt thermal shutdown of a system.
