Sense resistors have much lower resistance values (milliohms), tighter tolerances, lower temperature coefficients, and minimized parasitic inductance compared to standard resistors, making them suitable for accurate current measurement.
Current (I) = Voltage drop (V) / Resistance (R). Measure the voltage across the sense resistor terminals and divide by its known resistance value.
They provide real-time current measurement, allowing the control circuit to detect overcurrent conditions and trigger protective actions like reducing power or shutting down the circuit.
