The TLV4946xy is ideally suited to detect the rotor position in Brushless DC (BLDC) Motors used in industrial and
consumer applications, such as: air conditioning systems, pumps, washing machines, DVD players, rolling shutter,
etc. The sensor also provides a reliable switching for index counting with small pole wheels and large air gaps.
The TLV4946xy can also be used for index counting.
