The are many ways to measure current and Texas Instruments has a diverse portfolio to do exactly that!
Here are a few links to get you started measuring current with TI products:
If you don't know where to start with your current measurement design,…
While we wait, I'd like to recommend a few reference designs that address current sensing with high-voltage level translation requirements such as yours.
1) TIDA-00332 demonstrates the use of a current-output amplifier to level-shift a current…
There are several options you can take when measuring current off a negative voltage rail, but tradeoffs between them will need to be considered.
If you need a digital option you should consider reading over this reference design:
