Claim:
1. A two-wire hall-effect sensor comprising: a supply terminal; a return terminal; an intermediate terminal; a first voltage regulation circuit configured to regulate a voltage difference between the intermediate terminal and the return terminal to a first predetermined value when a voltage difference between the supply terminal and the return terminal exceeds the first predetermined value; a hall plate having a supply port, a return port electrically connected to the return terminal, and an output port; a second voltage regulation circuit configured to regulate a voltage difference between the hall plate supply port and the return terminal to a second predetermined value when a voltage difference between the intermediate terminal and the return terminal exceeds the second predetermined value; and signal processing and output stage circuits configured to vary an electrical current from the supply terminal to the return terminal in response to changes in the voltage difference between the hall plate output port and the return terminal.
