Set/Reset Strap
The set/reset strap is another spiral of metallization that couples to the sensor element’s easy axis (perpendicular to the
sensitive axis on the sensor die). The set/reset strap connections have a nominal resistance of 7.7 ohms with a minimum
required peak current of 0.5A for reset or set pulses. With rare exception, the set/reset strap must be used to periodically
condition the magnetic domains of the magneto-resistive elements for best and reliable performance.
A set pulse is defined as a positive pulse current entering the S/R+ strap connection. The successful result would be the
magnetic domains aligned in a forward easy-axis direction so that the sensor bridge’s polarity is a positive slope with
positive fields on the sensitive axis result in positive voltages across the bridge output connections. A reset pulse is
defined as a negative pulse current entering the S/R+ strap connection. The successful result would be the magnetic
domains aligned in a reverse easy-axis direction so that sensor bridge’s polarity is a negative slope with positive fields on
the sensitive axis result in negative voltages across the bridge output connections.
