Rdson current sensing

WebAs discussed previously, shunt resistors function as current measurement devices by dropping a precise amount of voltage for every amp of current through them, the voltage drop being measured by a voltmeter. In this sense, a precision shunt resistor “converts” a current value into a proportional voltage value. WebFor example, RDSon can increase by 60% or more if the junction temperature (Tj) increases from 25°C to 125°C. Compensation is needed to make RDSon current sensing accurate enough to meet stringent motor torque and speed control requirements. [0003] Variations in RDSon have been addressed by selecting transistor devices with close RDSon values ...
