ATS177中文资料Hall Effect Latches with Reverse Blocking Diode on the Supply Pin数据手册Diodes规格书

描述 Description

ATS177 is an integrated Hall effect latched sensor designed for
electronic commutation of brush-less DC motor applications. The
device includes an on-chip Hall voltage generator for magnetic
sensing, a comparator that amplifies the Hall voltage, and a
schmitt trigger to provide switching hysteresis for noise rejection,
and open-collector output. An internal bandgap regulator is used
to provide temperature compensated supply voltage for internal
circuits and allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, DO is turned
on (low). The output state is held until a magnetic flux density
reversal falls below Brp causing DO to be turned off (high).

简介

ATS177属于传感器变送器的磁性传感器-开关（固态）。由制造生产的ATS177磁性传感器 - 开关（固态）该系列产品使用固态技术来检测是否存在超过某个特定幅度和/或标示的磁场，并提供指示是否存在此类磁场的双态输出。它们与磁簧开关以及线性或罗盘型固态器件不同，前者通过使用移动机械部件来提供类似的功能，后者提供指示所施加磁场的强度和/或方向的可变输出。
