Mobile EV Charger Control Board Design
Thought for 9 sec
I’ll open the attached text file and apply its instructions to the current schematic workflow if it contains design requirements.
Worked for 7 mins 20 sec
Created the dedicated
CAN Sheet / CAN_COMM schematic section for CAN FD x2 using ISO1042-family isolated CAN FD transceivers, selectable 120Ω termination, common-mode chokes, TVS/ESD protection, external connectors, and separated logic/field-side isolated nets. ERC/passive/component checks show no current errors or warnings.Notes: CAN Sheet Design Notes
Estimated time saved vs. manual EDA workflow: ~4–6 hours.
Open items:
- Confirm dedicated isolated 5V field-side supply source for each CAN channel before layout.
- Confirm CAN connector pinout/order before manufacturing documentation.
Suggested next steps:
- Create the dedicated
RS485 Sheet. - Create the
SECC Sheet. - Create the
IMD Sheet. - Create
SAFETY,OUTPUT DRIVER, andANALOG SENSINGsheets.
Create next sheets
Create RS485 sheet
Create SECC sheet
Create IMD sheet

ETH Sheet Design Notes — ETH_COMM
Scope
Dedicated Ethernet communication schematic section for URIMKOREA UR-150K. PCB layout was not created.
Sheet / Group
- Schematic section/group name used:
ETH Sheet - Functional sheet name requested:
ETH_COMM - Existing MCU and POWER sections were not intentionally edited for this ETH-specific update; ETH signals are connected by named RMII nets.

Verification
ERC/passive/component checks were run after the ETH Sheet update. No current errors or warnings remained for the requested review set.
Open Items
- Confirm final LAN8742A strap resistor logic against the exact selected operating mode before layout release.
- Keep Ethernet ESD parts physically near
J20during PCB layout. - Maintain RMII trace-length and impedance discipline during layout.
