DRV5055-Q1: hall effect sensor DRV5055-Q1

Joel,

As far as I am aware, IP rating classifications are used to described whole system enclosures ability to resist particulates and moisture.  I'm not familiar with any individual components having this certification. 

A major benefit of Hall Sensors is that they can be placed in sealed enclosures separate from the magnet they detect. Magnetic fields readily permeate through many materials allowing the sensor to be adequately protected from external contaminants. Given this feature, I would expect a Hall Sensor such as DRV5055-Q1 could be designed into a system that achieves a very high IP rating.

Our devices do go through rigorous industry standard qualification processes which can be viewed here:

Among these are HAST tests.  These tests involve subjecting devices to specified temperature and humidity conditions.  Typically if a device fails this test, moisture is forced into the packaging of the IC and will cause delamination between the silicon and the external moulding.   Trapped moisture typically will cause additional electromechanical failures to occur to the device, so we do check to ensure the packaging is capable of protecting the silicon.
