Abstract
Magnetic current sensor, including: a sensor bridge circuit including a first and second half-bridges, each including two series-connected and diagonally opposed tunnel magnetoresistive (TMR) sensor elements, the TMR sensor elements including a reference layer oriented a single predetermined direction and a sense layer having a sense magnetization; a field line configured for passing a field current generating a magnetic field adapted for orienting the sense magnetization of the diagonally opposed TMR sensor elements of the first half-bridge and of the diagonally opposed TMR sensor elements of the second half-bridge in an opposite direction; such that a non-null differential voltage output between the TMR sensor elements of the first half-bridge and the TMR sensor elements of the second half-bridge is measurable when the field current is passed in the field line; the differential voltage output being insensitive to the presence of an external uniform magnetic field.
