DRV5056: DRV5056 related issues

Part Number: DRV5056

hi，

DRV5056 has poor consistency in Hall output after power outage and restart at regular intervals. Is it necessary to calibrate it after power on? If so, how to operate it?

Thanks！

    Hello Jeno,

    Thanks for posting to the sensors forum!

    Can you provide more details on what you by poor consistency after a power outage and on the restart at regular intervals?

    The DRV5056 is a ratiometric device that scales the output based on a given Vcc input voltage so this could be why there is a difference when there are power outages and if the Vcc voltage is not consistent.

    Best,

    Isaac
