If you're not using the Si85XX, then a solution with the THS4281 could be a solution with a shunt resistor. This circuit is found the the e2e community if you search UCC28070 and current sense.
Other Parts Discussed in Thread: OPA350 , ADS1256 , OPA320 , THS4281 Dear all,
We are currently using the ADS1256 in an application, with the VREF being generated from a voltage divider (it is a ratiometric application) and buffered by an OPA350 in essentially…
Hi Ken,
What you are seeing in the simulation can be expected in the real life circuit behavior. When you apply a large differential input voltage to the OPA227 (anything greater than about 1.2V) you will turn on two internal clamping diodes. This input…
Hi Maurizio,
Yes. UCC28070 has current synthesize which allow you to use resistor for current sensing. For amplifying I am using THS4281 in instrumental configuration and blanking puls .
Duration of blanking puls depend on switching frequency and Qg chosen…
Hi Imran,
I am using this circuit for current sensing. Beside THS4281 (HS amplifier) are 1G34 and 1G86 in function to suppress noise during OFF time. Working grate on 250kHz. Identical circuit is on CSB side. It is not simple like transformer but works…
