The TLE4946-2L is an integrated circuit Hall-effect sensor with low switching thresholds and low hysteresis. It is
specially designed for high sensitivity applications and is ideally suited to detect the rotor position in a BLDC motor.
Also for index counting with small pole wheels and large air gaps the sensor provides a reliable switching
information.

2.1
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 B
output on and a magnetic north pole exceeding B
