Hello: Can I connect a +/-5A MSC1802 device in path carrying 20Arms current? I know that we cannot measure the current. But will it cause any problem to the IC. The reason I am asking is, I would like to get accurate current measurement both at 5A and 20A. So If I connect two devices in series and measure current from both ICs, I can get high resolution and good current range. Except 20A will flow through the 5A devices. Let me know if this will be a problem.
Hi,
The sensor will rail when the current exceeds 5 A, but it’s completely safe and there’s no issue. You can just use it.
Sincerely,
Fox
