Overview

The TLV4946K and TLV4946-2K are high precision Hall Effect Latches with highly accurate switching thresholds for ambient operating temperatures up to 85°C.

The TLV4946K and the TLV4946-2K are available in a lead-free and halogen-free SMD package PG-SC59-3-5 package to meet current and future requirements.

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).

• Lead-free and halogen free SMD package

• Not suitable for automotive applications

Target Applications

   The TLV4946-2K 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 TLV4946K can be used in index counting applications with a magnetized pole wheel mounted on the axle of a motor.
