霍尔效应磁场传感器VG481V1

齿 速度

VG481V1包含双峰检测电路，该电路与霍尔效应元件耦合以检测铁齿轮齿目标轮的速度。当目标车轮经过传感器IC时，偏磁体提供一个变化的磁场。传感器IC参考峰值和槽磁电平起作用。传感器IC输出要么处于高状态，要么处于低状态，这对应于目标齿/槽特征。VG481V1集成电路由电压调节器、时钟/振荡器、霍尔元件、放大器、内部峰谷跟踪和保持电路、比较器和开路集电极输出级组成。传感器IC通过上电休息电路在低电压下保护不受异常操作的影响。输出电路包含短路保护。电压调节器包含反向连接保护。切片级别由存储的峰谷值派生。启动算法保持输出状态，直到切片级别达到稳定位置。VG481V1是零速度能力后，初始启动，只要电源应用。 The VG481V1 IC is offered in flat TO-92-style package with straight leads in bulk packaging which allows for a compact PC board layout Differentiation Provides lesser operate point variation. Value to Customers Uses a dual peak detecting circuit derived from the stored peak and valley values. This provides zero speed capability and more accurately tracks targets that exhibit run-out and other variations. AEC-Q100 qualified and often suitable for automotive applications. Provides higher accuracy. Features Back-biased speed sensor IC Zero-speed capable
