Description

Allegro MicroSystems recommendsAPS11900适用于所有新的可编程汽车2线霍尔效应开关IC设计。

A119X和A119X-F包括一个双线，单极，霍尔效应开关系列，可以在线端子在线上修整，以优化应用程序中的磁性开关点精度。后者（-F选项）是温度补偿，以与铁氧体磁铁配合使用。这些设备是在Allegro™高级BICMOS晶片制造过程中产生的，其实现了专利的高频，4相，斩波稳定技术。该技术在完全工作温度范围内实现磁稳定性，并消除了具有暴露于恶劣应用环境的单个霍尔元素的设备中固有的偏移。

The A119x and A119x-F family has a number of automotive applications. These include sensing seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position.

双线单极开关在成本敏感的应用中是特别有利的，因为它们需要更少的运行电线而与更传统的开路集电极输出开关相比。雷竞技最新网址此外，系统设计器本身地增益诊断，因为总是输出电流流动，这应该是两个窄范围中的任何一个。在这些范围内的任何当前级别都表示故障情况。

All family members are offered in three package styles. The LH is a SOT-23W style, miniature, low-profile package for surfacemount applications. The UA is a 3-pin, ultra-mini, single inline package (SIP) for through-hole mounting. The UB is a 2-pin single inline package (SIP) for through-hole mounting that integrates the power supply decoupling capacitor. All three packages are lead (Pb) free, with 100% matte-tin leadframe plating.
