  • Overcurrent detection of load circuits with temperature compensation
    Patent number: 9411349
    Abstract: An improved current limiting circuit including a switch having a first terminal and a second terminal, the first and second terminal configured to connect a power supply to a load. A first resistor connected in series between the first terminal and a first constant current source. A second resistor connected in series between the second terminal and a second constant current source. A control circuit configured to measure a voltage drop across the first resistor and compare the voltage drop to a voltage drop across the switch.
    Type: Grant
    Filed: November 13, 2014
    Date of Patent: August 9, 2016
    Assignee: LITELFUSE, INC.
