I need to make a heater circuit more intelligent.
Ok, but to do exactly what?
Does it matter in the context of the question?The existing design uses
a low-side switch with with a simple logic feedback to check for proper
operation.
Some safety feature, perchance?
Can you truly not think of any good reasons for wanting to monitorAn objective is to replace that with a device that will provide
a voltage output proportional to the heater current.
Not proportional to temperature? Just why do you need to know the current?

I can't personally think of a clearer way to ask "does anyone know ofI have found a few high-side switches that will do the job and I am starting
to lean that way.
Don't mean to be rude here, but this is a great example of 'how not to
ask a question'. Asking the right questions here will generally get you
very good answers.
