Hello Justin,
Thank you for using the TI forum. There are many different types of magnetic field sensors. Here are the bandwidths for some of our faster devices that we currently have in different categories:
Linear Hall Effect devices: 20kHz (ex…
전기화는 자동차 전력 시스템에 새로운 패러다임을 탄생시켰다. 설계가 하이브리드 전기차(HEV)이든 순수 전기차(EV)이든 해결해야 할 새로운 설계 과제가 있다. 이 기술 원고에서는 고전압 전류 감지의 몇 가지 주요 과제를 살펴보고, 당면한 설계 과정을 도와주고 간소화하는 추가적인 자료를 공유한다.
전류 감지에 대한 기본적인 소개는 e-북 “ 전류 감지 간소화 ”를 참조한다.

Hi Aravind,
At low current levels, resistor based current sensors probably work the best, we do offer a wide array of such devices, most of which are extremely low offset and low drift. You have the flexibility to size the sense_R. The common mode…
David,
Sorry for my delayed response. I do not have a step response for this at the moment but I can get one in a day or two. Can you tell me exactly what response you are looking for. A step from 0 -50A? Please note that the max bandwidth of the DRV425…
Hello Kazuhiko,
If you want an isolated solution, you may be able to use one of our magnetic solutions. These include the DRV401, DRV411, DRV425, and DRV421. Below I will outline what will be needed in addition to each of these parts in order for them…
Hello Yue,
We do not currently have a device that is low power with ±1mT sensitivity. However, you still have a few options that allow you to keep your existing magnet:
1. Use one of our existing low power parts (DRV5032 or DRV5012), and simply…
Hello Stuti,
This is correct. You will need to account for permeability of the flux concentrator. You might want to look into using the DRV425, which would be more accurate than DRV5053. You can learn about operational theory and use our calculators…
Hello Tony,
Thank you for using the TI forum.
First off, I would like to recommend that you look into using an inductive sensor for this application, such as the LDC0851. This is a "Differentially Compensated and Highly Accurate Inductive Switch…
Mayank,
Are you saying that you will see very fast transients up to 300V when you activate the FET? Our shunt based solutions currently only go up to around 80V in high side configuration, so you would be limited to a low side configuration where the…
