DRV5032: Product recommended

Part Number: DRV5032
Other Parts Discussed in Thread: DRV5023, , DRV5021

Hi sir,

Can you give me some Suggestion on product selection?

Requirement: Hall sensor switch

Hall sensor PCB system which have 8*8 hall sensor matrix

Pieces should be detected only at particular height

Output signal: Digital pulse

Height of detection : within 6mm from the surface

Power: 3.3~5v

Neodymium magnet detection : N42 6mm*1.5mm cylindrical size

thank u,

Regards,

  • Hayashi-San,

    Could you clarify which length is the diameter of the magnet?  The two geometries will behave differently. I assume there is an existing system and placement of the sensor cannot be adjusted much? 

    There is a calculator tool available on each of the DRV5032, DRV5023, or DRV5021 landing pages that can help with this sort of activity.  It allows the user to enter magnet dimensions and it will report the distances to trigger BOP and BRP for the various sensitivities.

    DRV5021

    DRV5023

    In the above cases, the calculator shows the maximum BOP points for the magnet settings provided. The closest device to the specific distance provided would be DRV5021A3.  In all of the cases above this value is based on the datasheet maximum value for BOP to ensure all device would trip by the advertised distance.
