霍尔效应芯片

磁传感器

霍尔IC是在霍尔元件中内置比较器和放大器的磁传感器,能够检测磁场强度,并输出数字信号。

根据检测模式,可分为锁存型(Latch)和开关型(Switch)两种。锁存型用于检测DCBL电机的驱动电路和转速,开关型耐磨损性强,可作为防污防水开关使用。

Ultra-small 0.76mm x 0.76mm 4-pin WL-CSP package latch-type Hall IC

AK8781

The AK8781 is a latch-type Hall IC with 60% reduction in package size from the conventional product AK8771.
Ultra-small package (0.76mm x 0.76mm x t0.38mm) is ideal for rotor position detection of small DC brushless motors.
In addition, it features fast response time and high temperature operation up to 125°C, so that it is suitable for applications requiring small size and high-speed rotation.
