Part Number: DRV425-BUSBAR-EVM Other Parts Discussed in Thread: DRV421 , DRV425 Tool/software: Team, Can the DRV425-BUSBAR-EVM card be used in a comparable setup as the DRV42 1 EVM below?
The DRV42 5 EVM does not seem to be suited in this case as the PCB is…
Part Number: DRV425-BUSBAR-EVM Other Parts Discussed in Thread: DRV425 Hello
I am trying to measure the rms noise level of DRV425 using its evaluation kit. I am using 24 bits ADC and ADC's measured rms noise level is under 10uv, but when I am connecting…
Part Number: BQ79718-Q1 Other Parts Discussed in Thread: DRV425-BUSBAR-EVM Hello,
I know that the BQ79758/BQ79652 have current sense inputs for a shunt measurement, but our Cells (Supercaps) are connected together with copper rails, which we can use one…
Hello Yoshikazu,
We currently do not have an ideal solution. Our hall sensors like the TMCS1126 have a differential to remove ambient filed. Our other hall sensor are design for position sensing and have properties ideal for magnet position sensing. The…
Part Number: DRV425-BUSBAR-EVM Other Parts Discussed in Thread: DRV425-Q1 , DRV425 Hello Javier,
Luke Andraka89 's data had 20 mVpp of noise with up to 40 mVpp.
The DRV425-Q1 data sheet says
- Noise is typically 17 nT rms from 0.1 to 10 Hz
- Noise density…
Part Number: DRV425-BUSBAR-EVM Other Parts Discussed in Thread: DRV425 , ENERGIA , MSP430FR4133 Team,
I am presenting a short overview of TI current and magnetic sensing innovations at the TI Rochester Innovation day to around 50 customers on December 1st…
Part Number: DRV425 Hello Team, Our customer is very interested in our product, DRV425. He want to know a roadmap of DRVxxx for sensing of high current. Do you have a plan to release a new product which is over 2mT ? He found some TI's reference designs in…
Hello Anand,
You can use magnetic sensing like the DRV411, DRV421 or DRV425 this will require some magnetic design. The DRV425 is the least magnetic design required https://www.ti.com/tool/DRV425-BUSBAR-EVM .
If you would like to use a shunt you could…
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) X 25 mm…
Hello Hayashi,
We don't have a solution for 5kV using either TMCS or Shunt-Based current sensing, the best solution we have for sensing current at 5kV will be using fluxgate devices such as the DRV421 and DRV425. Here is a reference design that uses…
