TDA51SCANHC Visão geral
An isolated CAN transceiver is an interface IC that provides galvanic isolation between a CAN protocol controller and the physical two-wire CAN bus. Isolation breaks ground loops, protects low-voltage circuitry from common-mode transients, and is essential where nodes span large ground potential differences. Within the signal-chain hierarchy, the TDA51SCANHC belongs to the isolated interface family: transceiver -> bus transceiver -> isolated CAN transceiver -> isolation and interface module.
Key features include 5000 VDC galvanic isolation, a common-mode transient immunity of 150 kV/us, and an integrated, efficient 5 V isolated power output that eliminates the need for a separate isolated DC-DC converter on the bus side. The device provides differential transmit and receive capability between the CANH/CANL physical bus and the protocol controller, and it operates across the full -40C to +125C industrial-extended temperature range.
A notable protection feature is the TXD dominant time-out function: if a hardware or software fault forces the TXD pin permanently low, the built-in dominant time-out timer prevents the bus from being blocked in a permanent dominant state, safeguarding network availability.
Typical applications include industrial fieldbus nodes (Profibus/CANopen gateways), battery management systems, motor-drive control networks, building automation, and medical equipment where isolation between the controller domain and the bus is mandated by safety or robustness requirements.
Design consideration: because the part integrates an isolated 5 V power stage, PCB layout must respect the creepage and clearance distances across the isolation barrier defined for the SOIC-16-300mil package, and the integrated power output should be decoupled per the manufacturer datasheet recommendations.

Aplicações típicas
TDA51SCANHC é adequado para 6 aplicaçãos: Industrial Fieldbus and CANopen Nodes, Battery Management Systems (BMS), Motor Drive and Inverter Control Networks, Building Automation and Elevator Control, Medical Equipment Isolation, Test and Measurement Instrumentation.
Industrial Fieldbus and CANopen Nodes
In factory automation, nodes frequently sit meters or hundreds of meters apart on a CANopen or proprietary CAN network, accumulating large ground-potential differences. The TDA51SCANHC fits this application through its ISO11898-2 compliance, 1 Mbps data rate for fast cyclic I/O traffic, and 5000 VDC galvanic isolation that breaks ground loops between cabinets. The 150 kV/us common-mode transient immunity tolerates the noise floor of motor drives and contactors sharing the same installation. In the circuit, the controller-side logic connects to the isolated transceiver inputs while CANH/CANL drive the twisted-pair bus terminated at 120 ohm at both ends. The integrated 5 V isolated power eliminates a separate isolated DC-DC on the bus side, reducing module size and cost per node. The dominant time-out function further protects network availability if a node controller fails.

Battery Management Systems (BMS)
A battery pack's cell-supervision electronics sit on a high-voltage, noisy domain, while the vehicle or inverter controller sits on chassis ground; CAN is the standard pack-level communication link and it must be isolated. The TDA51SCANHC addresses this with 5000 VDC isolation between the controller and the bus, 150 kV/us CMTI against switching transients from the inverter stage, and full -40C to +125C operation covering under-hood and outdoor energy-storage environments. Its 1 Mbps rate supports fast fault broadcast and state-of-charge messaging. Used between the BMS CAN controller and the pack-external bus, the part provides the entire isolated physical layer, including the 5 V isolated supply for the bus-side transceiver domain, which removes a discrete isolation converter from the high-voltage board and improves isolation-barrier integrity by reducing the number of components spanning the barrier.
Recomendado
Motor Drive and Inverter Control Networks
Variable-frequency drives and servo amplifiers generate steep dv/dt transients that corrupt ground-referenced communication unless the interface is isolated with high common-mode transient immunity. The TDA51SCANHC's 150 kV/us CMTI directly targets this environment, and its 5000 VDC isolation withstands the potential swings between the DC-link-referenced control electronics and plant-earthed networks. Its 1 Mbps CAN link carries setpoints, status, and fault frames with deterministic latency. Placed between the drive MCU's CAN controller and the machine-network cable, the module supplies its own isolated 5 V bus-side power, so no isolated bias rail must cross the barrier near noisy power stages. Designers should keep the module's primary-side decoupling tight and route CANH/CANL away from the gate-drive and DC-link switching loops to preserve signal integrity.
Recomendado
Building Automation and Elevator Control
Building networks span multiple floors and distribution boards, where earth potential differences and surge-coupled transients make direct-coupled CAN unreliable. The TDA51SCANHC provides the ISO11898-2 physical layer with 5000 VDC isolation, allowing each floor controller or elevator car electronics to float safely relative to the riser bus. Its -40C to +125C rating suits rooftop and machine-room installations, and 1 Mbps supports real-time car-position and door-control messaging. The integrated 5 V isolated power is particularly valuable in distributed nodes where adding a transformer-based isolated supply per node would dominate board cost. The TXD dominant time-out function keeps a single misbehaving controller from silencing the entire riser, an important availability property in life-safety-adjacent building systems such as fire-damper and access-control networks built on CAN.

Medical Equipment Isolation
Patient-connected medical devices require galvanic isolation of external communication ports to protect patients from fault currents, and CAN is commonly used inside imaging, laboratory, and monitoring equipment to link subsystems. The TDA51SCANHC's 5000 VDC isolation rating and 150 kV/us transient immunity provide the robustness expected at the equipment boundary, while its integrated 5 V isolated power lets the external-port side float completely from patient-side electronics. The SOIC-16-300mil package gives usable creepage across the barrier for layout planning, though final spacing must be validated against the applicable medical safety standard for the end equipment. The -40C to +125C operating range and 1 Mbps data rate cover autoclave-adjacent laboratory hardware and real-time sensor aggregation without protocol throughput compromises.
Recomendado
Test and Measurement Instrumentation
Bench and rack instruments interfacing to CAN-based devices under test benefit from an isolated CAN port that protects both instrument and DUT from ground conflicts. The TDA51SCANHC implements the complete isolated physical layer in one SOIC-16 module: ISO11898-2 transceiver, 5000 VDC barrier, and integrated 5 V isolated supply. Its 1 Mbps rate covers classical CAN fully, so the instrument can monitor or emulate nodes on vehicle, industrial, and battery-test benches without a separate isolated bias supply per channel - valuable when a rack instrument carries many isolated ports. The 150 kV/us CMTI survives switching loads on the DUT power supplies. The TXD dominant time-out ensures that a crashed DUT controller cannot hold the instrument's port in a blocked dominant state during long automated test sequences.

Principais diferenciais
- Integrated 5 V isolated power output (vs TDA5200)

- TXD dominant time-out fault containment (vs TDA5240)
Notas de projeto
The TDA51SCANHC spans a 5000 VDC isolation barrier inside an SOIC-16-300mil (7.50 mm) package. Keep primary-side (controller) and secondary-side (bus) copper pours fully separated with no traces under the isolation gap, and honor the creepage/clearance distances your safety standard requires - the package's internal spacing is the ceiling of what the layout can achieve. Place 0.1 uF + 10 uF decoupling at both supply pins, and decouple the integrated 5 V isolated power output per the datasheet application circuit.
Do not assume pin compatibility across the MORNSUN TDA5x isolated-interface family: suffixes encode supply, power-output, and data-rate options, so verify the pinout table of any candidate second source (TDA5200, TDA5211, TDA5230, TDA5240) against the TDA51SCANHC datasheet before qualifying. Also, the dominant time-out timer briefly limits minimum transmit pulse behavior at very low bit rates - confirm the timeout spec against your lowest intended CAN bit rate rather than assuming it is always transparent.
Route CANH and CANL as a tightly coupled matched pair with 120 ohm characteristic impedance and terminate only at the two physical bus ends; stubs to this transceiver should be kept under roughly 0.3 m at 1 Mbps. Keep the pair away from the drive and inverter switching loops; the module's 150 kV/us CMTI handles common-mode transients, but differential-mode coupling from poor routing can still cause bit errors. A common-mode choke at the connector, per typical ISO11898-2 application circuits, improves EMC margin in industrial cabinets.
