Free Quotecurrent through the inductor changes over time (di/dt) the energy stored in the magnetic field of the inductor creates a voltage (V = L × di/dt) that opposes (impedes) a further change in the current.

Free QuoteA chip cannot directly measure current. Instead, it measure the voltage drop across the current sense resistor and using ohm's law can compute the current, according to the formula, I= V/R. However, it must be noted as well that the voltage drop across the current sensor is going to be very low, because the resistance value is very low.
There are a several sensors that use magnetic field sensing for detecting the effects of current flow. These can be very effective for detecting very large currents or when isolated measurements are required. The most common sensor for measuring current is a current sensing, or shunt, resistor.
Current sensing is a fundamental requirement in a wide range of electronic applications. Motor speed controls and overload protection This application note focuses on the concepts and fundamentals of current sensing circuits.
An ideal current sensor has the ability to completely reject the common-mode voltage component of the measurement, and only measure the current of interest. In-package magnetic current sensors like the TMCS1100 pass the phase current through a package leadframe, which creates an internal magnetic field.
The ratio of the output voltage is proportional to the magnetic field. During the current sensing process, the current is measured by measuring the magnetic field. The output voltage is very low and needs to be amplified to a useful value by using a high gain amplifier with very low noise.
Since there is no direct connection between the sensing circuitry and the system, the system is inherently isolated. This makes magnetic current sensing an excellent choice for high-voltage or dynamic current measurements. In the past, indirect current sensing was typically only used to measure currents 100A or greater.
