Abstract: The circuit includes two output terminals (OUT1, OUT2) for connection to the terminals of a load (L), first and second pairs of electronic power switches (Q1, Q4; Q2, Q3) which are connected between the output terminals (OUT1, OUT2) and the two poles of a direct-current voltage supply (Vs) so as to form an H-shaped structure with the load (L), and a driver circuit (C1, C2) for selectively making the electronic power switches of the first pair (Q1, Q4) of the second pair (Q2, Q3) order to cause a current to flow through the load (L) in one direction or the other respectively, and for preventing the electronic switches (Q1, Q3; Q2, Q4) which are connected between the same output terminal (OUT1; OUT2) and the two poles of the voltage supply (Vs) from conducting simultaneously.

Abstract: A magnetic sensor is formed by a fluxgate sensor and by at least one Hall sensor integrated in a same integrated device, wherein the magnetic core of the fluxgate sensor is formed by a magnetic region that operates also as a concentrator for the Hall sensor. The magnetic region is manufactured in a post-machining stage on the metallization layers wherein the energizing coil and sensing coil of the fluxgate sensor are formed; the energizing and sensing coils are formed on a semiconductor substrate housing the conductive regions of the Hall sensor.
