6. Motor Current Shunt Resistor Selection

Rohit is designing a 24V DC motor control board and wants to monitor motor current to detect overload conditions. 

The motor can draw up to 2A. 

He decides to use a 0.1Ω shunt resistor in the current path so the controller can sense current from the voltage drop across it. 

Help him select a 2512 size SMD current-sense resistor that supports accurate measurement, safe power dissipation, low resistance drift with temperature, and reliable operation in industrial temperatures.
