JuMar,
Thanks for using the forum to get your question answered. I will quickly give a summary of the trade offs for each.
Closed Loop:
More Accurate
More immunity to outside magnetic fields due to magnetic core
Limited range due to compensation coil…

Hi, My customer has been looking for alternative solutions of isolated current sensor from Allegro for their BLDC motor current sensing. ACS723: High Accuracy, Galvanically…
Part Number: DRV425 Hello, I have the DRV425 EVM and tested it with a magnet. I got see a voltage at Vout when I move the magnet. Is it also possible to detect a static (reposing) magnet with the DRV425?

Part Number: DRV425EVM Other Parts Discussed in Thread: DRV425 , DRV421 , TIPD205 I need to measure a DC current of 100 milliamps with the DRV425 EVM kit. I would like to know how this component works. I am not familiar with the concept of this product. …
Hi Javier Thank you so much.
What current limit would be safe for the part? 10mA at 3V?
Regarding QFN package soldering we have quite a long experience. Except for one Atmel part whose pads gets electrically open after say cleaning by manual soldering…
Hello Praveen,
Thanks for reaching out on the forum. Your requirements are quite challenging to meet for any single current shunt monitor. To measure up to 2000A with the INA226, you would need a 41uohm resistor, which you would probably need to create…
Hello Sabarinath,
We have a reference design on this that you can leverage, link below. You may need to get more averages and use two evm to get remove a common field like the on contributed by the earth's magnetic field. Another issue could be the orientation…
Thank you Javier,
we ordered the EVM kit.
Does the DRV425 require any type of calibration?
If so, is the DEV KIT already calibrated or not?
Many thanks
Rick
Other Parts Discussed in Thread: DRV425 Hi
These days, I am considering use the DRV425 for high current sensor and I did test by using DRV425 EVM.
For our project, I have several questions.
Block diagram of the datasheet shows the fluxgate sensor and compensation…
