cs5463 problems
Hi all,
I have been facing problems with my power meter design.
I don't know why, but I have already lost 4 units of the power meter ic I use (CS5463 form Cirrus Logic).
I noticed that even with no load applied to the circuit (hall sensors), sometimes, the CS5463 ic is lost. For the others times the ic was lost, there was load applied to the hall sensors (current and voltage).
The IC receives signals from the opamps and communicates with an PIC18F2620 through SPI interface.
I don't know if the I need to implement any protection for the power meter ic. I guess I should, but I don't know how and what one.
Here is the schematic:
Any help is more than appreciated.
Thank you,
Rodrigo
