We've previously respun the CN0359 circuitry into a PCB to reduce the form factor, and we're in the process of doing it again to make it even smaller. In this respin, we're hoping to make a couple modifications to fit the form factor we need and for it to properly work in our application and want some advice.
First, is there a smaller alternative to the EMI filters (PN BNX025H01L) used in the power circuitry? Our application is powered off a battery pack, so we're also considering just removing them altogether.
Second, are there any recommendations on ICs and their integration to provide isolation between the data and power signals?
