Design a circuit and PCB for testing CN3082 battery charger IC

We require an evaluation board to be designed to characterize the performance of a battery charger IC, the CN3082 from Consonance Electronics.

Design Requirements:

- Concurrent measurement of input and output voltages and currents, and voltage of temperature pin and charge status pin with resolution of 2 mV and 2 uA and accuracy of 5 mV and 5 uA, using an onboard multichannel ADC. To achieve the required accuracy, calibration trimmer pots may be added to the design.

- Use low-value current shunts and op-amp buffered voltage taps to minimize measurement disturbance of circuit under test.

- Measurement devices (op-amps, ADCs, etc.) will be powered separately and will communicate through an I2C bus to a off-board device through a standard pin header.

- Measurement devices must have suitable filtering as well as input protection so that they are not damaged if their power is disconnected while the device under test remains powered.

- CN3082 device under test will have headers for general input and output connections to the board, as well as a JST header for solar input connection to a 6V, 600 mA solar panel, and an SMD 18650 battery holder for output.

- Wherever possible, components should be chosen that are SMD, and are easy to hand assemble (at least 0.5mm pin pitch, 0603 - 0805 passives, etc.)

- Some specific devices may need to be utilized in the design, as we may have parts already on hand. More details will come.

Deliverables:

- Board schematic to be checked by our team so that any revisions can be made by us before going forward.

- List of which signals connected to which ADC channels, and conversion factors (in mV/count or uA/count).

- Bill of materials which shall consist of all parts required, and shall be readily available from suppliers such as Digikey and Mouser (with exception of CN3082 IC).

- Layout of a finished 2-layer board, with signals and components properly labeled, not larger than 100mm x 80mm.

- Finished Gerber files, ready for manufacture.

All design work must be done using KiCAD software.
