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. MH281特点和优点 l CMOS霍尔IC技术
