Current measurement
« on: July 30, 2007, 03:23:29 AM »
I need to be able to measure the current to my stepper motor. I will be measuring it between the motor driver, and the power supply.
The current will be around 2A average so i want a component that can handle around 3-4 A.

Any ideas?

I have checked out the ones on maxim-ic, but they all can only handle milliamps.
Thanks
