MH 281 is an unipolar Hall effe sensor IC. It incorporates advanced chopper
stabilization technology to provide accurate and stable magnetic switch points. The design,
specifications and performance have been optimized for applications of solid state switches.
The output transistor will be switched on (BOP) in the presence of a sufficiently strong
South pole magnetic field facing the marked side of the package. Similarly, the output will be
switched off (BRP) in the presence of a weaker South field and remain off with “0” field.
The package te is in a lead (Pb)-free version was verified by third party organization.
Green package is available by customer’s option.
