DRV5033-Q1: Some user cases questions ask

Part Number: DRV5033-Q1
Other Parts Discussed in Thread: DRV5033

Hi team

I would like to ask that is there an application cases for using the magnet to wake up and turn off the screen? The magnet may change with time and the surrounding environment, and whether there is a situation where the magnetic force attenuation causes the trigger to fail? Need your side to share with some information to avoid this phenomenon or tell us some application scenario about this question, thank you!

  • Hello Zirui,

    Thanks for reaching out on the forum.  The application you are interested in sounds equivalent to what we present in our transition detection tech note and TIPL.  As the magnet changes with temperature and time, so does the DRV5033.  Temperature impacts BOP, BRP, BHys specifications as well as the magnetic offset of the device as indicated in figures 4, 6, 8 , and 10 of the datasheet.  You should plan to have your magnet placed such that your desired trigger positions will have a higher magnetic field than the BOP max and and a weaker field than BRP min with respect to where your DRV5033 is located.  What kind of magnet is your customer using?

  • Hi Simons

    Thank you and I will send the reference documents to customer. In addition, do you have any data on the number of working times and life time of the DRV5033Q1?(Under -40~150℃  working temperature)Customer may want to have the durability test report, thank you.
