Overview

The TLV4946-2L is a high precision Hall Effect Latch with highly accurate switching thresholds for ambient operating temperatures up to 85°C.

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 µs).

• High ESD performance (± 4 kV HBM).

• Digital output signal (open-drain).

• Not suitable for automotive applications

Target Applications

The TLV4946-2L 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 TLV4946-2L can also be used for index counting.
