Hello Javier Contreras,
I have one more question with regards to the DRV425 magnetic field operating range. As per the data sheet, the maximum operating magnetic flux density is 2mT. We planned to use these devices in differential mode for current sensing…
Part Number: DRV425-Q1 Hello Javier:
Thanks for the help with my prior questions.
There are three different documents that TI has published with slight variations on the connections of the Driver and the compensation coil
1.In the EVM, the DRV425-Q1…
The are many ways to measure current and Texas Instruments has a diverse portfolio to do exactly that!
Here are a few links to get you started measuring current with TI products:
If you don't know where to start with your current measurement design,…
Hello Chloe,
The DRV425 is a bipolar output so it will measure positive and negative relative to its axis of sensitivity. The default condition of the DRV425EVM is to have Vref = VDD/2. In this case if the output voltage is VDD/2 =Vref then your field…
Sam,
INA253EVM can measure the current up to 15A from -40°C to 85°C so this should be fine.
AMC1301EVM can be used but you please review the User's Guide as I am not as familiar with this device and EVM.
The DRV425 measure magnetic field and…
Hello Tom,
thank you very much for your two answers. I've been on vacation, that's why this response is a bit late. I am sorry for that.
I had a look at your AMC1301 isolation amplifier. Your assumption that we might need an isolation amplifier…

FYI. The header pins on the DRV425 EVM are ferromagnetic. The pins are phosphor bronze plated with nickel and then gold. David
Part Number: DRV425 Hi Team,
My customer is working on a design that uses the DRV425 and they have a couple questions that I’d like to get your help with.
It is worth noting that in their design, they take the single ended measurement of each opposed…
Part Number: DRV425EVM Other Parts Discussed in Thread: DRV425 , , ADS1256 I'm looking to use the DRV425 for an amateur earth field magnetometer, and the EVM avoids having to handsolder this tiny part
I swapped R1 to 470 ohm to maximise sensitivity…
Part Number: DRV425 Hi Javier
Could I request the FEMM models along with any supplementary information for TIDUAZ4 reference design please? Both the standard +/- 100A as well as the modified version boosting the current rating.
I'm especially interested…
