tle4946-2k高精度霍爾效應(yīng)鎖存器

　　The TLE4946-2K is a high precision Hall effect latch with highly accurate switching thresholds for operating temperatures up to 150°C.

　　The TLE4946-2K is an integrated circuit Hall-effect sensor with low switching thresholds and low hysteresis which make it ideally suited to detect the rotor position in a BLDC motor commutation application.

　　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.
