What is the best current sensor IC for measuring a voltage source (30 V) and 6 A

(1/2) > >>

Jony_1:
Hello guys,

I need the smallest current sensor IC (because I don't have much space on my PCB) that has these specifications:

    Has good isolation (more than 500 V)
    Works with 3.3 V (I need to connect to an MCU)
    Measures currents up to 6 A.

I will be grateful if you could introduce me to some ICs that you worked with.

Psi:
Does it need the current to pass through the chip, or use external sense resistor?

Jony_1:
Thank you Psi for your comment. Both strategies work fine for me.

TI has a range of isolated amplifiers for current sensing: https://www.ti.com/isolation/isolated-amplifiers/products.html#p1694=Current%20sensing
