TJF1052IT/1Y Visão geral
A CAN transceiver (also called a CAN PHY) is the physical-layer interface between a CAN protocol controller and the differential CAN bus. In industrial systems, galvanic isolation between the low-voltage controller domain and the high-voltage bus domain protects sensitive microcontrollers from ground loops, surge events, and high common-mode voltages. The TJF1052i family extends the standard CAN transceiver by embedding this isolation barrier inside the IC, simplifying PCB layout and reducing BOM count compared to discrete isolator-plus-transceiver designs.
Key features include integrated 1 kVrms isolation, 2 Mbps CAN FD (Flexible Data-rate) capability, low loop delay suitable for CAN FD frames, thermal protection, bus-dominant time-out, and a silent mode for selective wake-up. The device supports the ISO 11898-2 physical-layer standard and is specifically targeted at industrial automation, energy distribution, and medical equipment applications where reinforced isolation is mandatory.
Internally, the TJF1052i combines a capacitive- or transformer-based isolation barrier with a CAN transceiver core on a single silicon die. The wide-body SOIC package provides the required creepage and clearance distances for 1 kVrms isolation, while the exposed pad aids thermal dissipation during sustained bus transmission. The result is a CAN transceiver that satisfies both functional isolation and basic insulation requirements in a single chip.
Typical applications include industrial PLC communication modules, grid-tied smart-meter networking, photovoltaic inverter CAN buses, battery management system (BMS) communication links, electric-vehicle charging-station controllers, and isolated sensor networks in process automation. Designers reach for the TJF1052i when they need CAN connectivity in a high-voltage environment without the complexity of a multi-chip isolated solution.
When designing with this part, mind the wide-body 7.50 mm SOIC footprint - it is wider than a standard 150-mil SOIC, so PCB land pattern and creepage must accommodate it. Also confirm that the upstream 5 V or 3.3 V controller rail is well decoupled; the isolated bus side derives its own internal supply through the on-chip isolation transformer/charge pump, so no external isolated supply is required.

Aplicações típicas
TJF1052IT/1Y é adequado para 6 aplicaçãos: Industrial PLC CAN Communication Modules, Smart Meter and Energy Distribution Networks, Photovoltaic Inverter CAN Bus Interface, Battery Management System (BMS) Communication, EV Charging Station Controller Interface, Medical Equipment Isolated Sensor Networks.
Industrial PLC CAN Communication Modules
The TJF1052IT/1Y suits industrial PLC communication modules because its integrated 1000 Vrms galvanic isolation eliminates the standalone isolator-plus-DC-DC chain that would otherwise stand between a PLC's CAN controller and the field bus. The 2 Mbps data rate per the NXP datasheet covers classical CAN and CAN FD frames, and the 20 kV/µs CMTI rating per DigiKey's parametric data rejects fast transients generated by the PLC's switching I/O and adjacent motor inverters. Placed on the PLC's CAN connector interface, it preserves the 16-SOIC wide-body footprint that maintains the creepage and clearance required for industrial control cabinet insulation coordination.
Recomendado
Smart Meter and Energy Distribution Networks
In smart-meter and energy distribution networks, the TJF1052IT/1Y is used at the meter's CAN interface because the integrated 1000 Vrms isolation per the NXP datasheet protects the meter's low-voltage controller from mains-borne ground potential differences. The 2 Mbps CAN FD data rate can carry both metering telemetry and tariff data in the same physical wire. The wide-body 16-SOIC footprint delivers the creepage required by IEC 62053-style meter safety standards, and the high 20 kV/µs CMTI prevents transient-induced bit errors that would otherwise distort billing data during grid switching events.
Recomendado
Photovoltaic Inverter CAN Bus Interface
PV inverters place a CAN bus between the inverter and the string-monitoring combiners, and the TJF1052IT/1Y is well chosen because the integrated 1000 Vrms isolation per the NXP datasheet protects the controller from high DC bus common-mode voltages present in the inverter. The 20 kV/µs CMTI per DigiKey's parametric listing suppresses the IGBT-switching noise generated inside the inverter's power stage. With CAN FD capability at 2 Mbps, the same transceiver can carry both inverter telemetry and module-level monitoring data over the bus.
Recomendado
Battery Management System (BMS) Communication
For BMS master-controller communication to distributed battery modules, the TJF1052IT/1Y provides galvanic isolation per the NXP datasheet (1000 Vrms) that protects the master from the stacked battery cell voltages that may reach hundreds of volts. The 2 Mbps CAN FD data rate per the datasheet is sufficient for cell telemetry plus balancing commands, and the wide-body 16-SOIC footprint satisfies the creepage required by automotive and energy-storage safety standards. The integrated isolation means no isolated DC-DC supply is needed on the high-voltage battery side.
Recomendado
EV Charging Station Controller Interface
EV charging station controllers use the TJF1052IT/1Y at the connector side because its integrated 1000 Vrms isolation per the NXP datasheet blocks high DC bus voltages from reaching the controller's logic domain. The 20 kV/µs CMTI per distributor parametric data withstands the large common-mode transients caused by IGBT power conversion in fast-charging stations. 2 Mbps CAN FD capability carries authentication, telemetry, and charging-state updates over the same isolated bus without needing a discrete isolator plus DC-DC chain.
Recomendado
Medical Equipment Isolated Sensor Networks
In medical equipment with isolated sensor networks, the TJF1052IT/1Y provides the galvanic isolation barrier that patient-connected devices need between sensing electrodes and host electronics. The 1000 Vrms isolation per the NXP datasheet, combined with high 20 kV/µs CMTI per distributor listings, suppresses defibrillator and electrocautery transients that would otherwise corrupt communication. With 2 Mbps CAN FD and an integrated isolation transformer, the design avoids the bulky isolated DC-DC that often compromises medical-device form factors.

Principais diferenciais
- Integrated 1000 Vrms galvanic isolation in a single 16-SOIC wide-body chip (vs Discrete TJA1052 + standalone digital isolator + isolated DC-DC)
- 20 kV/µs CMTI rating for harsh industrial switch-mode environments (vs TJA1052 (non-isolated))
- Wide-body SOIC footprint maintains creepage for reinforced isolation (vs 16-SO narrow body)
Notas de projeto
The TJF1052IT/1Y requires the wide-body 16-SOIC footprint (0.295 inch / 7.50 mm body width) for the 1000 Vrms isolation rating - do NOT use the narrower 150-mil SOIC land pattern, because creepage and clearance distances for the rated isolation will fail. Provide guard traces or keep-out areas underneath the package body to maintain the rated insulation.
Place a 100 nF decoupling capacitor as close as possible to VCC1 (controller-side supply pin 1), and a second 100 nF cap on VCC2 (pin 15, bus-side internally-derived supply) to stabilize the internal isolation supply. Per NXP datasheet layout guidance, bulk capacitance should be added only on the controller-side rail - the isolated bus-side uses the on-chip charge-pump; do NOT load VCC2 with bulk capacitance that exceeds the on-chip regulator current rating.
CAN bus termination (typically 120 ohms between CANH and CANL, with optional split termination 60 ohms + 4.7 nF) should be placed at the end of the bus and NOT adjacent to the TJF1052IT/1Y unless the device is at a stub endpoint. The 20 kV/µs CMTI will protect against fast transient noise, but bus reflection from misplaced termination can still corrupt CAN FD frames at the 2 Mbps top end of the device's bandwidth.
Do not assume the TJF1052IT/1Y is automotive-grade - per the NXP product page the TJF1052i family is targeted at industrial applications and is not AEC-Q100 qualified. For automotive CAN-isolator designs, consider NXP's TJA1057 automotive transceivers combined with an automotive-qualified digital isolator rather than reusing this part in safety-relevant car subsystems.
