Hall effect sensor based, so it measures AC/DC/Whatever. Output is microcontroller friendly.

i can use sense resistor , but not with the ground lead , only with the Vcc lead 🙂
i had decided to use a 0.01r/5w at +vcc at a cost of increase of ripple at mosfet positive rail of my h bridge.But i think the sense resistor is somewhat inductive.My pcb is ready but in the future i will try other elegant solution .

Why you can't insert a small shunt in the range of 0.025 ohm in the ground lead?
Also, have you considered using the Vcc lead as the ground for whatever control circuit you are employing?
Hi Peranders,
I saw allegro`s site ,
I think is the kind of easy and fast solution of current sense.
Have you had the opportunity to test one of Them?How they perform?What was your max current?
tks

Hi Eva,
have you had any significant increase in mosfet ripple inserting this kind of shunt resistor?
Did you use ,sometime ago,cooper or brass barr as shunt ?How about the performance?

its a bit complicated , had to do it for my work ...🙂Eva said:
floating ground circuit is not an option also 🙂
Eva can u please answer my 2nd question in my other thread on this page , u are the only one who can 😀
peranders:
yes , i saw it , looks pretty cool , but its in a smd package
hate 'em ! 🙂- Status
