MH281是一颗单极霍尔开关，可用作电器的单向开关.
MH281 is an unipolar Hall effect 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 type is in a Halogen Free version was verified by third party organization. Halogen Free package is available by customer’s option.
