HAL805K中文资料Programmable Linear Hall-Effect Sensor数据手册TDK-Micronas规格书

描述 Description

Introduction
The HAL805 is a recent member of the Micronas family of programmable linear Hall sensors. It offers open circuit detection and individual programming of different sensors which are in parallel to the same supply voltage.

特性 Features

– high-precision linear Hall effect sensor with ratiometric output and digital signal processing
– multiple programmable magnetic characteristics in a non-volatile memory (EEPROM) with redundancy and lock function
– open-circuit detection (ground and supply line break detection)
– for programming an individual sensor within several sensors in parallel to the same supply voltage, a selection can be done via the output pin
– temperature characteristics are programmable for matching all common magnetic materials
– programmable clamping function
– programming through a modulation of the supply voltage
– operates from −40 °C up to 150 °C ambient temperature
– operates from 4.5 V up to 5.5 V supply voltage in specification and functions up to 8.5 V
– operates with static magnetic fields and dynamic magnetic fields up to 2 kHz
– overvoltage and reverse-voltage protection at all pins
– magnetic characteristics extremely robust against mechanical stress
– short-circuit protected push-pull output
– EMC and ESD optimized designMajor Applications
Due to the sensor’s versatile programming character istics, the HAL805 is the optimal system solution for
applications such as:
– contactless potentiometers,
– angle sensors,
– distance measurements,
– magnetic field and current measurement.
