TLI4946K, TLI4946-2K, TLI4946-2L High Precision Hall Effect Latches for Industrial and Consumer Applications About this document Overview The TLI4946xy is a high precision Hall Effect Latch with highly accurate switching thresholds for ambient operating temperatures up to 125C. The TLI4946K and the TLI4946-2K is available in a PG-SC59-3-4 package, the TLI4946-2L in a PG-SSO-3-2 package Features 2.7 V to 18 V supply voltage operation. Operation from unregulated power supply. High sensitivity and high stability of the magnetic switching points. High resistance to mechanical stress by active error compensation. Reverse battery protection (-18 V). Superior temperature stability. Low jitter (typically 1 s). High ESD performance ( 4 kV HBM). Digital output signal (open-drain). Not suitable for automotive applications Target applications The TLI4946xy 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 TLI4946xy can also be used for index counting.
