Classification: CPC H  G | IPC H

Claim 7:
8. A method, comprising:
detecting a switching current of a power module flowing between a Kelvin pin and a source pin of the current detector and outputting a voltage derived from a differential component of the switching current;
filtering the voltage output from the current detector with a resistor-capacitor filter;
integrating the filtered voltage;
converting an integrated analog voltage into a digital voltage to sample the digital voltage;
applying a scaling constant to a sampled integrator output value and outputting a sampled switching current; and
compensating for a current by removing a temperature dependent direct current resistance (DCR) effect from the sampled switching current,
wherein the filtering is high-pass filtering.
