1. A current sense circuit, comprising:

  • a shunt resistor in a current path for measuring current in the current path;

    a sense resistor coupled to the shunt resistor for dividing current supplied to the shunt resistor; and

    a resistance value for the sense resistor being selectable such that a ratio of the shunt resistor value to the sense resistor value produces a gain suitable for establishing a range of current measurements to cover a range of sensed current.
