Current Sensing is required in many applications to determine the amount of current flowing through a circuit. Current sensors are available in the market to sense the current. Current sensors can be:
- Resistor based current sensing
- Hall Effect based current sensing
One more classification of the current sensing is:
- Isolated
- Non-isolated
Resistor based current sensing can be:
- High side current sensing
- Low side current sensing
Below is the topology of low side current sensing:
Below is the topology of high side current sensing:
Below are the differences between resistor based current sensing and hall sensor based current sensing:
