Hi Bob.
We have used numerous INA194 chips from Texas Instruments. They run from the supply that's being monitored.
Can send the circuit and layout image if you wish

What are people using on their cubesats (etc) for current sensors?
The MAX-471 we have been using since 2001 (PCSAT) in all our designs are now obsolete.
We want a chip with internal shunt and up to say 2 amps or so.

We use INA199B3 on the Fox-1 CubeSats.
I can provide you the schematic or you'll find it in the 2015 Space Symposium Proceedings page 340, if you are interested.
