  • Publication number: 20210072294
    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.

  • Patent number: 10877079
    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, an output choke inductor, and an output pin. The power module also includes a first sense terminal coupled to the PCB trace, a second sense terminal coupled to the output pin such that a resistance between the first sense terminal and the second sense terminal is defined by a resistance of the PCB trace and a resistance of the output pin, and a control coupled to the first sense terminal and the second sense terminal. The control is adapted to measure a voltage between the sense terminals, and to determine a current through the PCB trace and the output pin based on the measured voltage and the resistance between the sense terminals.
