DRV5032: DRV5032DG

Tool/software:

Hi,

I have purchased a sample of the 80hz ultra low power unipolar hall sensor and I have given it 3.3v supply.

Even without having the ring magnet passing it, the current consumption measured using a micro ammeter is 51uA.

Please suggest why this maybe happening as I am using the OUT1 pin on the pcb and its left unconnected at the moment and yet  the high current consumption.

Regards,

Jyoti

    Hi Jyoti,

    Thank you for posting to the Sensors forum!

    Are you able to measure the current consumption with an oscilloscope? The 5.7uA typical current consumption in the datasheet is an average of the device as it cycles through it's low powered state (which should be in the order of nA) and it's peak consumption state(2mA typ). Depending on how low your ammeter can actually measure, it could be the case that it's not able to accurately detect the low power period which can contribute to the high CC that you are measuring.

    Best,
