Claim 8:
9. A method for generating a temperature compensated sensed current for each phase of a driver in a multi-phase switched mode power supply, the method including:
determining when a temperature sensor is directly coupled to an input of the driver;
configuring the driver in a master mode to generate a digital temperature signal when the temperature sensor is coupled to the input of the driver and configuring the driver in slave mode to generate the digital temperature signal when the temperature sensor is not coupled to the input of the driver;
transmitting the digital temperature signal to a plurality of phase-current sensors, each of the plurality of phase-current sensors corresponding to a phase of the multi-phase switched mode power supply; and
adjusting each of the plurality of phase-current sensors according to the digital temperature signal to generate a temperature-compensated sensed current at an output of each phase-current sensor.
