Abstract
A method and device for temperature monitoring of a power transistor formed in a semiconductor die comprising are disclosed. A side of a temperature-sensing resistor disposed in the semiconductor die is coupled to a voltage input side of the power transistor. A controller coupled to a second side of the temperature-sensing resistor is configured to detect a voltage across the resistor and trigger a temperature related corrective action using the detected voltage.
