Annie,
I am sorry there is no off the shelf core that can be purchased. One needs to be designed for the DRV421. Please use the documentation and tools provided on the product page.

Hello Phuc,
If you are going to have a maximum sensitivity of 0.5 mT, then I recommend the DRV425 (a fluxgate sensor), which is a linear magnetic sensor with a full scale range of ±2mT.
Based on your design requirements, you may be able use a linear…
Dean,
The current level you are trying to measure with the magnetic field is very low and does not generate a high magnetic field for the DRV5055. The DRV425 can sense a magnetic field with more sensitivity but you would need to gain up your magnetic…
Hello Kyrre,
The only Hall devices that we currently have in the X2SON package are the DRV5011 (latch), DRV5012 (latch), and the DRV5032 (switch). Besides these, the only other magnetic field sensor that we currently have in a thinner package than…
RAH,
The DRV425 has a full scale sensing range of approximately 2mT with an offset max of 8uT. The range you are needing is very small and you would need to take a few thing into account if using the DRV425. First if you place your current of interest…
Hi,
None of our non-isolated current sense amplifiers (CSA) can withstand 220V by themselves without suffering breakdown. However there are circuits that can enhance their capability, as demonstrated by these two designs –

Hello SK Loo,
Thank you for using the TI forum.
If you need an omnipolar Hall switch specifically, the closest option we have for your requirements is the DRV5033FA, but that has a typical B OP of 3.5mT and a max B OP of 6.8mT. So, this may not quite…
Hi Ron,
Are you making any progress here? Another device you might look into is the DRV425 - we have an application note describing the use of this device in (essentially) a differential configuration for use in bus bars. You can find more detail here…
Hello Daniel,
There are a couple options based on how much more sensitive you need the device. The suggestions I will give below presume that you need a linear output, and not a switch or latch output.
The DRV5055A1 is a bipolar linear Hall device…
Part Number: TIDA-01467 Other Parts Discussed in Thread: DRV425 , , TIPD205 Hi team,
I promoted TIDA-01467 for my customer engineer and he has strong interesting. But the customer would like to measure the current up to 100A. One issue could be if PCBA…
