TLV4946K数据手册传感器变送器的磁性传感器-开关（固态）规格书PDF

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

优势:

应用 Application

• To detect the rotor position in Brushless DC (BLDC)
• Index counting applications with a magnetized pole wheel mounted on the axle of a motor.

简介

TLV4946K属于传感器变送器的磁性传感器-开关（固态）。由制造生产的TLV4946K磁性传感器 - 开关（固态）该系列产品使用固态技术来检测是否存在超过某个特定幅度和/或标示的磁场，并提供指示是否存在此类磁场的双态输出。它们与磁簧开关以及线性或罗盘型固态器件不同，前者通过使用移动机械部件来提供类似的功能，后者提供指示所施加磁场的强度和/或方向的可变输出。
