DRV5013-Q1: Output under VCC=2.5V

Part Number: DRV5013-Q1

Dear, Sir.

My customer is asking about the output when VCC is under 2.5V.

VCC range is defined from 2.7V to 38V.

According the datasheet description, I am gussing it would be Hi-Z?

Sorry to ask about this kind of matter. I would like to double-confirm.

Please give your advice.

Best Regards,

H. Sakai

    Hello Sakai-san,

    It is true that the output pin will have Hi-Z during it's power-up sequence. However, this device has a pull-up resistor on the output, so the output voltage will be the same as the voltage that the line is being pulled up to while the device is off. 

    It is important to note that although the device is not guaranteed to be active until it has 2.7V, it is possible that the device turns on at a lower voltage, such as 2.5V or 2.25V as an example. If a south magnetic field is present when the device is turned on, then the device will pull the output low.

    Dear, Mitch-san. 

    Thank you so much for your advice. 

    I understand it is depended on the VCC voltage which DRV5013-Q1 become active under 2.7V. 

    Is it possible to assure such VCC volatge?

    Sorry to ask about this kind of matter. 

    Best Regards,

    Hello Sakai-san,

    It is not possible to assure a specific VCC under 2.7V where the device could become active because this could be different from device to device. As a result, we can only assure what is in the datasheet, which is that the device will be active at 2.7V.
