DRV5032: Current draw

TI-CSC
Genius 9600 points
Part Number: DRV5032

Hello E2E Experts,

Good day.

I am planning on using the DRV5032 is a battery-operated product for asset tracking. 

I am the Principal hardware Engineer for the project.

I am designing the power supply. 

Looking at the DRV5032 specification the peak current consumption is 2.7ma but the average current consumption max is 1.8uA.

On page 7 of the DRV5032 specification the ICCPK Peak current consumption id 2.7ma max. Since I am designing this into a battery-operated product I want to know under what condition the DRV5032 requires 2.7ma max.

Thank you in advance for your support.

Regards,

CSC

    Thank you for reaching out with your question.  Normal operation for DRV5032 will have the device in a low power sleep which it will periodically awaken from, take a sample and then return to the low power state.  Please refer to the example diagram from the datasheet

    The peak Icc is only required during t-active, which is specified here:

    The peak Icc value occurs while the sensor is forcing a current through the Hall-element, which with an applied magnetic field will produce a measurable internal voltage that is used to evaluate the state of the applied field.

    Thanks,
