  • Temperature-Compensated Current Monitoring
    Publication number: 20160190792
    Abstract: Systems, methods and media for current monitoring are provided herein. An exemplary method may include: receiving a temperature of a power MOSFET, the temperature being sensed by a temperature sensor; determining a resistance of the power MOSFET using the received temperature; receiving a voltage across the power MOSFET, the voltage being measured by a differential amplifier; calculating a current provided to an electrical load by the power MOSFET using the determined resistance of the power MOSFET and the received voltage; comparing the calculated current to a predetermined threshold; and switching the power MOSFET to an off state in response to the calculated current exceeding the predetermined threshold.
