Are there any hall current sensors with discrete(adjustable) output?

There are chips like ACS712, ACS724 and some others.
But these provide linear output, while I'm looking for discrete output, under 1A current range.
Like if current is less than 0.1A, there's no output, if current exceeds 0.1A, there's logical "1" on output.

I know that by adding an opamp to above mentioned chip can do the trick, but I'm looking for a complete, single chip solution, with adjustable threshold.
