AH372中文资料High Temperature High Sensitivity Hall Effect Latch数据手册Diodes规格书

描述 Description

AH372 is a single-digital-output Hall-Effect latch sensor with internal pull-up resistor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an output driver with a pull-up resistor. An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
When the magnetic flux density (B) perpendicular to the package is larger than operation point (BOP), output is switched on (OUT pin is pulled low). The output state is held on until a magnetic flux density reversal falls below BRP. When B is less than BRP, the output is switched off.
The AH372 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack), SC59 and SOT23 packages.

简介

AH372属于传感器变送器的磁性传感器-开关（固态）。由制造生产的AH372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。
