Applications
The PTCAN1044DRQ1 is designed for CAN network interfaces in automotive ECUs covering body control modules, powertrain control units, and chassis safety systems that require AEC-Q100 reliability across the full automotive temperature range of -40°C to +125°C. Its fault-protected transceiver protects against wiring harness short circuits and load dump transients common in vehicle environments. The device also suits industrial CAN fieldbus nodes in factory automation equipment where ISO 11898-2 physical layer compliance and a robust differential interface are mandatory.

Frequently Asked Questions
What AEC-Q100 grade rating does PTCAN1044DRQ1 carry, and what temperature range does it guarantee?
The PTCAN1044DRQ1 is qualified to AEC-Q100 Grade 1, which mandates qualification testing across an ambient temperature range of -40°C to +125°C. This grade is required for under-hood automotive applications such as engine control units and transmission controllers where temperatures regularly exceed the +85°C commercial rating.
What CAN bus data rate and bus fault tolerance does PTCAN1044DRQ1 support in automotive wiring harnesses?
The transceiver supports ISO 11898-2 high-speed CAN at up to 1 Mbps on the differential bus pair. It tolerates bus faults of ±16 V beyond the supply rails, protecting against wiring short circuits to battery (12 V to 24 V) or ground, as well as load dump transients up to 40 V that are typical in 12 V automotive electrical systems.
How does PTCAN1044DRQ1's SOIC-8 package compare to smaller alternatives for compact automotive ECU designs?
The SOIC-8 package measures 4.9 mm × 3.9 mm with a 1.27 mm pitch, offering a balance between compact board area and hand-soldering or standard SMT assembly compatibility. Designers needing a smaller footprint can consider TI's TCAN1044 in a 3 mm × 3 mm WSON-8 package, which reduces footprint by approximately 50% at the cost of requiring finer-pitch assembly equipment.
For a new automotive CAN node design, what is the PTCAN1044DRQ1 system-level schematic requirement beyond the transceiver?
A typical application requires only a 100 nF decoupling capacitor on the 5 V supply pin, a 60 Ω split termination network (two 30 Ω resistors) at each bus end, and optional ESD protection diodes rated above ±12 kV HBM on CANH and CANL lines. The transceiver's internal bus protection circuitry handles ±16 V fault conditions, simplifying the external protection BOM to just 3–5 passive components per node.
