Description

New applications for linear output Hall effect sensors, such as displacement and angular position, require high accuracy in conjunction with redundant outputs. The Allegro A1359 programmable, linear, Hall effect sensor IC has been designed specifically to achieve both goals. The features associated with this linear device make it ideal for use in automotive and industrial applications requiring high accuracy, and this temperature-stable device operates across an extended temperature range: –40°C to 150°C.

Features and Benefits

• Dual tracking outputs: analog voltage output and pulse width modulated (PWM) output

• Matched analog and PWM outputs enable user to detect various output error conditions

• Factory-programmed offset, sensitivity, and polarity

• Sensitivity temperature coefficient (TC) and QVO/QD temperature coefficient programmed at Allegro® for improved accuracy

• High speed chopping scheme minimizes quiescent voltage output (QVO) drift across temperature

• Temperature-stable QVO and sensitivity

• Output voltage clamps provide short circuit diagnostic capabilities

• Wide ambient temperature range: –40°C to 150°C

• Immune to mechanical stress

• Enhanced EMC performance for stringent automotive applications

A1359属于传感器，变送器 > 磁性传感器 - 线性，罗盘（IC）。Allegro MicroSystems制造生产的A1359磁性传感器 - 线性，罗盘（IC）该系列产品可用于将磁场强度作为一个可变数量进行测量，而相比之下，类似产品仅检测是否存在强度超过某个限值的磁场。常见的应用包括测量地球磁场，以类似于传统罗盘的方式进行定向，市面上的一些器件允许以相对于磁场的物理方向直接读取测量值。
