Joachim,
Our DRV425 expert Javier is out on holiday today and tomorrow, as TI observes New Years as a holiday. I have made him aware of your questions, and we will get you some answers Monday when we return to the office.
In the meantime, there is…
Hello Annie,
The accuracy of these devices can meet the accuracy be the challenge is in the magnetic design. This is where we can limited guidance but the biggest error will come from the magnetic design. The DRV401 is more likely to function better…
Hello Dmitry,
The voltage and current will limit you to our hall sensors and flux-gate sensor. Our present hall sensors selection are more limited to sensing from a magnet and have some bandwidth and accuracy tolerances that may not meet you needs but…
Hello Divyanshu,
The only design guide that uses the DRV425 is http://www.ti.com/tool/TIDA-01467 . This is because all the other use a magnetic core and a magnetic feedback in order to measure the current. They do not use the electrical connection as…
zehua,
The DRV425 is a fluxgate device, which is similar to hall but typically more sensitive. As such, we have found a great way to measure large DC currents with the DRV425 by using two of them inserted into a copper (or other conductive metal) bus…
Part Number: DRV425 Tool/software: I want to connect multiple DRV425 like described in the busbar application note but more than just one pair. Is there a way to do this? For example 4 DRV425 where 2 build one pair in differential mode and the second…
Part Number: DRV425 Application: Busbar current sensing up to 1500 A
Current-sensing Method: Dual DRV425 devices for differential measurement
Application Requirement
Busbar current sensing up to 1500 A
Busbar Geometry: 12 mm Height (Thickness…
Sid,
Thanks for using E2E!
We have a great resource in our R_SHUNT calculator that allows you to enter your design values and determine sensitivity amongst several other parameters in the design. I have posted a link here .
A challenge here for…
Part Number: TIPD205 Other Parts Discussed in Thread: DRV425 Tool/software: We've been working on measuring current using the DRV425 IC, for which we made a proper setup using a variac (for variable current supply) along with the TIPD205. We ended up…
