MH282
Specifications
Sensitivity Unipolar Hall Effect Switch
MH282 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 (B
OP
) 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 (B
RP
) 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.
Features and Benefits
DMOS Hall IC Technology.
Reverse bias protection on power supply pin.
Solid-State Reliability.
Chopper stabilized amplifier stage.
Unipolar, output switches with absolute value of South pole from magnet.
Operation down to 3.0V.
High Sensitivity for direct reed switch replacement applications.
100% tested at 125℃ for K Spec.
Custom sensitivity / Temperature selection are available.
Good ESD Protection.
