  • Current sense shunt resistor circuit
    Patent number: 7135891
    Abstract: Current through a wire is sensed with a shunt resistor and a sense resistor in a current divider circuit. The values of the shunt resistor and sense resistor are related to provide a specified gain ratio to increase a dynamic range of current measurement. The sense resistor is a trimmable resistor, the configuration of which can be discerned from a look-up table based on a level of precision needed for current measurement. The two resistors can also be related by thermal coefficients to improve linearity of current measurements.
    Type: Grant
    Filed: August 22, 2005
    Date of Patent: November 14, 2006
    Assignee: International Rectifier Corporation
    Inventors: Massimo Grasso, Aldo Torti, Andrea Merello, Jonas Aleksandravicius

  • High current sense resistor and process for its manufacture
    Patent number: 6489881
    Abstract: A low resistance high current sense resistor is formed on a semiconductor die using conventional semiconductor processing techniques. The resistor die has one or two resistive layers which are photolithographically divided into a plurality of series and parallel resistor sections connected to first and second main terminals. First and second sense terminals are connected across one or a pattern of plural ones of the resistors to produce an output related to the current between the main terminals. Fusible links permit the trimming of the final resistance value.
