A119X和A119X-F：可编程，斩波稳定，双线霍尔效应开关

亚博棋牌游戏Allegro Microsystems推荐APS11900.for all new programmable Automotive 2-wire Hall-Effect switch IC designs.

The A119x and A119x-F comprise a family of two-wire, unipolar, Hall-effect switches, which can be trimmed by the user at end-of-line to optimize magnetic switchpoint accuracy in the application. The latter (-F option) are temperature compensated for use with ferrite magnets. These devices are produced on the Allegro™ advanced BiCMOS wafer fabrication process, which implements a patented high-frequency, 4-phase, chopper stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.

A119X和A119X-F系列具有许多汽车应用。亚博尊贵会员这些包括传感座椅轨道位置，安全带扣的位置，罩/行李箱锁定和变速选择器位置。

Two-wire unipolar switches are particularly advantageous in cost-sensitive applications because they require one less wire for operation versus the more traditional open-collector output switches. Additionally, the system designer inherently gains diagnostics because there is always output current flowing, which should be in either of two narrow ranges. Any current level not within these ranges indicates a fault condition.
