Hi,
I'm using this particular motor driver IC(http://www.mouser.com/ds/2/427/sip2100-519775.pdf) to supply bi-directional current to a magnetic torque rod. I intend to control the Input A & B pins with my arduino uno. I also powered the IC with my arduino board and obviously got laughed at by my friends, I didn't know that arduino uno boards could only supply a maximum of around 200mA of current. So I'd like to ask:

I also powered the IC with my arduino board and obviously got laughed at by my friends, I didn't know that arduino uno boards could only supply a maximum of around 200mA of current. So I'd like to ask:
- I am planning to power the IC with a DC power supply this time, I plan to give it a Vcc of 5V, how much source current should I supply to this IC?
- On the datasheet, I am not sure what the Sa and Sb (pins 1 and 4) pins are, the datasheet says they are driver output returns, but I have no idea what that means.
