Original question:

DRV5032: What meaning have shown in magnetic response curve of sensor if B is either of more than BOP or less than BRP?

DRV5032: trigger range of unipolar functionality

Part Number: DRV5032

Condition : Supposing that initial position of OUT2 is kept as high level, so B is increasing until what value is able to trigger OUT2 which is changed as low level 

Question1 : From the spec, Bop is from 1.2mT to 3.9mT for trigger. Is it correct that any value in the range is able to trigger OUT2 which become to lower level ? For example, if B is increasing to 1.2mT firstly, please advise if it is to trigger immediately

    Andrew,

    For each device there will be a specific threshold which will trigger Bop and likewise for Brp.  Assuming a known ideal field, this exact threshold can vary from device to device.While most devices will operate near the typical value, it's possible to have a device with a threshold anywhere between the max and min specifications.  It is typically safest to design the solution to work with the maximum threshold to ensure any device will work.  In the example you bring up, it would be best to make sure that the device would see at least 3.9 mT at the desired position.

    Thanks,

    Scott
