TJF1052IT/5Y Обзор
An isolated CAN transceiver is a device that bridges a host microcontroller's CAN protocol controller to the physical two-wire differential CAN bus while maintaining galvanic isolation (no direct electrical connection) between the high-voltage bus side and the low-voltage logic side. This category sits within the broader hierarchy of CAN transceivers -> automotive/industrial bus transceivers -> interface ICs -> wired communication ICs. Galvanic isolation is required for safety, ground-loop elimination, and noise immunity when the bus operates at high common-mode voltages relative to the host controller.
Key features of the TJF1052IT/5Y include 20 kV/us common-mode transient immunity (CMTI), integrated DC-DC isolation power, ±58 V bus fault protection, and thermal shutdown. The device supports the ISO 11898-2 standard CAN physical layer and is compatible with both classic CAN and CAN FD (Flexible Data-rate) frames up to 2 Mbps. Power dissipation is bounded by the SOIC-16W package's thermal resistance, making it suitable for industrial automation nodes and battery management system peripherals.
Architecturally, the TJF1052IT/5Y combines an on-chip coreless-transformer isolation barrier, an isolated CAN physical layer, and a fully integrated isolated power supply. This single-chip integration replaces the typical 3-chip solution (CAN transceiver + digital isolator + isolated DC-DC), reducing BOM count, PCB area, and design complexity while improving reliability through fewer solder joints.
Typical applications include industrial automation PLC fieldbus nodes, solar inverter CAN interfaces, battery management system (BMS) slave modules in e-mobility, and railway signaling where reinforced isolation is mandatory. The wide bus fault tolerance also makes it suitable for 24 V truck and 48 V mild-hybrid automotive environments.
When designing with this device, note that the integrated isolation removes the requirement for optocouplers, but the PCB layout must still preserve the 5 kV creepage and clearance at the package level. Decoupling capacitors close to the VCC pins on both sides of the isolation barrier are critical for stable CAN signal integrity.

Типичное применение
TJF1052IT/5Y подходит для 6 применениеs: Industrial Automation PLC Fieldbus Nodes, Battery Management System (BMS) Slave Modules, Solar Inverter CAN Interface, Railway Signaling and Rolling Stock, Electric Vehicle Charging Stations, Medical Equipment CAN Bus Isolation.
Industrial Automation PLC Fieldbus Nodes
The TJF1052IT/5Y's 5 kVrms galvanic isolation makes it ideal for industrial PLC fieldbus nodes where 24V or higher common-mode voltages exist between controller cabinets and motor drive stages. The 20 kV/us CMTI ensures the CAN signal integrity is not corrupted by fast transients from adjacent switching inverters and contactors. The integrated isolated DC-DC eliminates the need for a separate isolated power supply, reducing PCB area by approximately 40% compared to discrete CAN + digital isolator + DC-DC solutions. Typical placement: between the PLC CPU's CAN controller and the CANopen / DeviceNet bus connector with the isolation barrier aligned to the cabinet earth ground.

Battery Management System (BMS) Slave Modules
The TJF1052IT/5Y enables reliable CAN communication between BMS slave modules and master controllers in e-mobility battery packs. The 5 kVrms isolation barrier protects the low-voltage master CAN interface from the high-voltage battery stack common-mode transients during switching events. The 2 Mbps data rate supports CAN FD frames carrying per-cell voltage, temperature, and SOC data at high update rates. The wide bus fault tolerance guards against transients on the 400V or 800V battery bus. Typical deployment: 16-SOIC placed near the high-voltage battery connector with creepage/clearance maintained to the 5 kV isolation specification.

Solar Inverter CAN Interface
The TJF1052IT/5Y provides isolated CAN connectivity between solar inverter power stages and external monitoring/grid-sync controllers. The 5 kVrms isolation is essential for separating the high-voltage DC bus (up to 1500V) from the low-voltage communication interface required by IEC 62109 safety standards. The 20 kV/us CMTI rejects noise from the inverter's high-frequency PWM switching, maintaining CAN bus integrity even at peak inverter load. Integrated isolated power removes the BOM cost of a separate isolated DC-DC module. Typical application: inverter CAN bus reporting to a data acquisition system or smart-grid controller.

Railway Signaling and Rolling Stock
The TJF1052IT/5Y meets railway isolation requirements for CAN bus communication in train control systems and rolling stock. The 5 kVrms reinforced isolation complies with EN 50155 railway standards, and the -40C to +125C operating temperature range covers the full railway environmental envelope. The integrated isolation simplifies the safety certification path by reducing component count in safety-critical signaling circuits. The 2 Mbps CAN FD support enables high-bandwidth train diagnostics and predictive maintenance data alongside legacy 500 kbit/s signaling.
Рекомендуется
Electric Vehicle Charging Stations
The TJF1052IT/5Y provides isolated CAN communication in EV charging stations (EVSE) between the charging controller and the EV's BMS via the charging inlet CAN bus. The 5 kVrms isolation meets IEC 61851 and IEC 62196 safety requirements for EV charging, where isolation between the grid-connected power stage and the vehicle communication port is mandatory. The wide bus fault tolerance handles DC fast-charging transient events. The single-chip integration accelerates design and reduces charger station BOM cost. Typical deployment: between the EVSE controller CAN interface and the charging connector pilot/signaling pins.
Рекомендуется
Medical Equipment CAN Bus Isolation
The TJF1052IT/5Y provides patient-safe isolation in medical equipment that uses CAN for internal communication between subsystems, such as infusion pumps, patient monitors, and imaging systems. The 5 kVrms isolation barrier meets IEC 60601-1 patient leakage requirements when properly implemented on the PCB with adequate creepage. The 2 Mbps data rate supports high-resolution imaging data transfer between subsystems. The integrated isolated power simplifies medical device certification by reducing isolation barrier count. Typical deployment: between patient-connected modules and the main equipment chassis ground.

Заметки по проектированию
Estimated: The 16-SOIC (7.50 mm wide) package provides approximately 8 mm of internal isolation creepage. To preserve the 5 kVrms isolation rating, maintain at least 8 mm of PCB creepage distance and 8 mm of clearance between the logic-side and bus-side copper traces and pads. Use a slot in the PCB (cutout between SOIC pins 4 and 5, and between pins 8 and 9) to increase creepage if needed. Under the package, do not route any traces crossing the isolation barrier - all logic-side signals must terminate on the pin 1-4 side and bus-side signals on the pin 9-16 side.
Decoupling: Place a 100 nF ceramic capacitor as close as possible to VCC1 (pin 1) and a separate 100 nF ceramic capacitor as close as possible to VCC2 (pin 16). Add a 4.7 uF bulk capacitor on VCC1 to handle the integrated DC-DC switching transients. The on-chip isolated DC-DC requires sufficient bulk capacitance on both rails to maintain regulation - insufficient capacitance may cause bus-side VCC2 to drop below the CAN transceiver UVLO threshold during heavy CAN bus loading.
Bus termination: The TJF1052IT/5Y does not include on-chip CAN bus termination resistors. You must add a 120 ohm resistor between CANH and CANL at each end of the CAN bus segment. Split termination (60 ohm + 60 ohm with a capacitor to ground) is recommended for improved EMI. Failure to terminate the bus will cause signal reflections and CAN communication errors at higher data rates, especially in CAN FD mode at 2 Mbps.
