Hall-sensor voltage in BLY172s-24v-4000

Hello all,

the BLY172s-24v-4000 in DRV8312-C2-KIT has a Hall-sensor. From the schematic of DRV8312, it is clear that the supply voltage for this sensor is 5V.

But I can not find any other info/datasheet about this Hall-sensor.

So far as I consider, I can/wanna/have to supply the Hall-sensor with 3.3V. Don't know whether 3.3V also fits the Hall-sensor.

Did anyone already do it or know some details about this Hall-sensor?

Best regards,

Long

    Long,

    I sent a request to the supplier....Anaheim Automation.  The datasheet I have for the motor provides no information on this.  Will let you know what I find.

    Long,

    Anaheim responded that 4.5V is the minimum voltage to power the halls.

    Hallo Ryan,

    thanks for your answer. In my application I will drop the 5V Hallsensor interface.
