Hi,

for a new design my customer is looking for a TI alternative to these LEM devices:

Is there something I can propose?

Thanks

Hello Josef,

We have components that would normally go inside that devices like that for example the DRV401, DRV411 and the DRV421. The customer would then need to design the magnetics (cores, sensor, mechanical design). The other alternative is our in-package Hall sensors but they are not able to go up to 25A. They are the TMCS110X family. You can find those options here. https://www.ti.com/sensors/magnetic-sensors/hall-effect-current/products.html
