HMC1043
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.
Typically a reset pulse is sent first, followed by a set pulse a few milliseconds later. By shoving the magnetic domains in
completely opposite directions, any prior magnetic disturbances will be completely erased by the duet of pulses. For
simpler circuits with less critical requirements for noise and accuracy, a single polarity pulse circuit may be employed (all
sets or all resets). With these uni-polar pulses, several pulses together become close in performance to a set/reset pulse
circuit. Figure 1 shows an H-Bridge Set/Reset circuit that will generate both set and reset pulses to the set/reset strap.
Additional information and examples on set/reset pulse circuits can be found in our application notes AN201 and AN213.
