Precise magnetic switching thresholds and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. Offset voltages, generated by temperature induced stress or overmolding are canceled and high accuracy is achieved. The IC has an open collector output stage with 20mA current sink capability. A wide operating voltage range form 2.7V to 18V with reverse polarity protection up to -18V makes the device suitable for a wide range of applications. A magnetic south pole with field strength above Bop turns the output on and a magnetic north pole exceeding Brp turns it off.
