Abstract

The disclosure is directed to a circuit on a substrate, such as a leadframe package, that includes shunt to measure current. The shunt is an arched conductor positioned to bridge over a die mounted on the package with voltage measurement terminals of the die electrically connected to the shunt. The techniques of this disclosure determine the shunt material, shunt size and shape to accurately control the value of the resistance of the shunt. The arrangement of the die and the shunt may include advantages of maintaining a small package size and allow accurate temperature compensation. The shunt may be long enough to have a measurable resistance that may be used to determine the current through the shunt. In some examples, the arrangement of the die and the shunt may provide additional structural support to the circuit.
