描述 Description

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.

特性 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

? Index counting applications with a magnetized pole wheel mounted on the axle of a motor.

簡介

TLV4946K屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由制造生產(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(gè)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(dòng)機(jī)械部件來提供類似的功能，后者提供指示所施加磁場的強(qiáng)度和/或方向的可變輸出。
