On $50sat we used the ZXCT1009 three terminal sensor. This requires an external shunt but allows allot of flexibility for scaling the sense voltage and now has "flight heritage".

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.
