集成电路芯片资料和参数

芯片型号:MT1401

功能特点

•These Hall-effect sensors are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +125°C, and are more stable with both temperature and supply voltage changes.

•Each device includes a voltage regulator for operation with supply voltages of 2.8 to 18 volts, hall plate with dynamic cancellation system, temperature compensation circuitry, chopper stablized smallsignal amplifier, Schmitt trigger, and an open drain output to sink up to 50 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits.

•This sensor family includes most widely used industry package type with same die inside

•双极霍尔需要两个磁极分别控制高电平与低电平,此特性可与多极环形磁铁或者其他类似结构相互配合,产生不同应用例如无刷电机位置传感、速度里程测量等。

•CMOS工艺:采用混合信号以及斩波除噪技术,使得采用该工艺的IC磁参数具有良好的一致性和高灵敏度,特别适用于需要对磁场强度做出精确反应的应用。
