Abstract
An electronic device with thermal fault protection wherein temperature sensors are not employed to detect an unbalanced thermal runaway condition. The device employs resistor networks to monitor a voltage differential that can be affected by transistor leakage currents. Configuration of the electronic device in this manner provides accurate and reliable fault protection from both unbalanced thermal runaway conditions and some manufacturing defects without the need for temperature sensors. A method is also provided.
