TLV4946K傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）規(guī)格書PDF中文資料

TLV4946K屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由英飛凌科技股份公司制造生產(chǎn)的TLV4946K磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來檢測是否存在超過某個特定幅度和/或標(biāo)示的磁場，并提供指示是否存在此類磁場的雙態(tài)輸出。它們與磁簧開關(guān)以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機械部件來提供類似的功能，后者提供指示所施加磁場的強度和/或方向的可變輸出。

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.
