... S/R- BASIC DEVICE OPERATION The Honeywell HMC6042 magnetoresistive sensor circuit is a pair of sensor and analog support circuits to measure magnetic fields. With power supply applied, the sensor converts any incident magnetic field in the sensitive axis direction to a differential voltage output. In addition to the bridge circuit, the sensors have two on-chip magnetically coupled straps; ...

... Figure 1 shows a quick and dirty manual pulse circuit for uni-polar application of pulses to the set/reset strap. ASIC Within the HMC6042, the application specific integrated circuit (ASIC) performs the set/reset strap drive and sensor amplification functions. The ASIC has its positive power supply rails broken into VDD1 and VDD2 elements to supply the sensors/amplifiers and set/reset driver respectively ...
