DRV5032: Probability density function for Bop & Brp

Art Mecina

Part Number: DRV5032

Hello Guys,

Good day.

Our customer wants to understand how we determine the probability density functions for Bop & Brp? Also if one sample will always turn-on/off at the same point or if there is a randomness for the on/off level within a single hall effect sensor.

Thanks in advance!

Hi Art,

Instead of designing systems based on the PDF, we recommend designing the system based on the min/max Brp/Bop specs. These min/max specs take into account any drift as well as device to device variations. The following post has more info on this recommendation:

In addition, the below video about the operating and release point specs in Hall switches may also be helpful for this design:
