Package, Footprint, and Handling

The TCAN1042HGVDRBRQ1 is offered in TI’s DRB‑code WSON‑8 (3 x 3 mm) package, ideal for densely populated PCBs and compact automotive modules. The “R” in the orderable code indicates Tape & Reel for high‑volume, automated assembly lines.

Package: DRB (WSON‑8), 3 x 3 mm
Pin Count: 8
Mounting: Surface mount (SMT)
Handling: Follow TI’s package drawing and assembly recommendations for stencil design, reflow profile, and land pattern. Always consult the datasheet/package documentation for exact footprint dimensions.

Standards Compliance and Electrical Interface

ISO 11898‑2 compliance ensures interoperability with HS‑CAN and CAN FD networks.
Up to 5 Mbps CAN FD data rate supports higher throughput versus Classical CAN while maintaining robust physical‑layer signaling.
Integrated fault and ESD protection on CANH/CANL improves resilience against real‑world stress events found in automotive and industrial environments.
Nominal 5 V supply aligns with the standard power domain for CAN transceivers.

Low‑Power and Silent Operation

The transceiver supports silent/low‑power operating modes, helping minimize current draw when network activity is low or when nodes must remain quiescent. In safety‑critical or energy‑constrained systems, silent mode also prevents the transceiver from actively driving the bus while still allowing monitoring of bus activity, aiding diagnostics and controlled wake strategies designed at the system level.

Environmental Robustness

Temperature Range: −40°C to +125°C for full automotive capability
Qualification: AEC‑Q100 (Q1), indicating TI’s automotive‑grade qualification
EMI/EMC Considerations: The device incorporates an EMI‑optimized driver/receiver design, supporting low‑noise operation on the bus. Combine this with good layout and appropriate common‑mode chokes or transient suppressors as required by the system design and compliance plan.

Applications

Automotive in‑vehicle networking (body, powertrain, chassis, ADAS)
Industrial CAN networks and gateways
Infotainment and telematics modules
Battery management systems (BMS) and EV subsystems

These application spaces benefit from the combination of CAN FD bandwidth, small WSON‑8 footprint, and ruggedized physical‑layer protection. By using the Texas Instruments TCAN1042HGVDRBRQ1, designers can reduce board area while retaining the robustness expected of an automotive CAN PHY.

Design‑In Guide and Practical Tips

While every design is unique, the following checklist reflects common best practices for ISO 11898‑2 CAN FD transceiver implementations:

Supply and Decoupling
Provide a clean nominal 5 V rail as required by the device.
Place decoupling capacitors close to the VCC pin(s) with low‑inductance return to ground.
Bus Termination
Use 120 Ω termination at each end of the CAN bus, per ISO 11898‑2 practice.
For CAN FD at up to 5 Mbps, maintain controlled impedance and minimize stub lengths.
EMC/ESD Strategy
Consider common‑mode chokes and ESD/transient suppression devices at the connector as needed by your compliance plan.
Keep CANH/CANL differential pair tightly coupled with symmetrical routing to reduce emissions and improve immunity.
Grounding and Layout
Maintain a solid reference plane; avoid splits under the transceiver where possible.
Route CANH/CANL as a matched‑length differential pair with consistent spacing.
Low‑Power/Silent Mode Integration
Use the device’s silent/low‑power capability to reduce current draw when nodes are inactive.
Coordinate system‑level wake and diagnostics behavior in the MCU and network stack.
Thermal and Mechanical
Follow TI’s package drawings for land pattern, solder mask, and reflow profile.
Observe handling guidelines for moisture sensitivity and ESD.

Note: For any device‑specific pin behaviors, timing parameters, and electrical thresholds, consult the TI datasheet.
