Abstract:
According to some aspects of the present disclosure, power modules having current sensing circuits, and corresponding sensing methods, are disclosed. Example power modules include a printed circuit board (PCB) having a PCB trace, a first sense terminal coupled to the PCB trace at a first location, and a second sense terminal coupled to the PCB trace at a second location such that a resistance between the first and second sense terminals is defined by a resistance of the PCB trace between the first location and the second location. The power module further comprises a control coupled to the first sense terminal and the second sense terminal, the control adapted to measure a voltage between the first sense terminal and the second sense terminal and determine a current through the PCB trace based on the measured voltage and the resistance between the first sense terminal and the second sense terminal.
