デュアル ホール効果ラッチ

当社では、1 つのウエハー上で 2 次元方向に検知可能なデバイスを作成するために、従来の平面ホール効果技術と、垂直ホール効果技術 (AVHT) を組み合わせました。

こうした垂直ホール センサー ソリューションは新しく、より小型で、コストの低いシステム フォーム ファクタを実現し、マグネット ピッチまたはエア ギャップに依存しない直交信号を提供することで、モーター / エンコーダに革新的進化をもたらします。また、すべての新規デバイスは、機能的安全性に対応する ISO 26262 に準拠して設計されています。

Application Note

Improved Speed and Direction Sensing Using Vertical Hall Technology

The A1262 2D dual-channel Hall-effect sensor IC is offered in a 5-pin SOT23W surface-mount package, as well as a 4-pin SIP through-hole package. It features operation with traditional planar—as well as vertical—magnetic field direction.

Application Note

Ring Magnet Speed Sensing for Electronic Power Steering

Proper control of Electric Power Steering (EPS) systems requires both speed and direction information from the steering input shaft. This control will typically come from both high-resolution speed information and fairly coarse position information.
