Product details

Automotive CANbus transceiver for 5 Mbps CAN FD networks

It supports data rates up to 5 Mbps, making it suitable for high-speed in-vehicle communication such as powertrain, body electronics, and advanced driver-assistance systems.

Rated at 5 Mbps, the TCAN1144DRQ1 supports CAN FD (flexible data-rate) frames, which allow payloads larger than the classical 8-byte limit and faster arbitration-to-data transitions. This matters when a design needs to push firmware updates or high-resolution sensor streams over the CAN bus without adding a second network. The half-duplex architecture keeps the pinout simple — one TXD, one RXD, and the CANH/CANL differential pair — matching the standard CAN physical layer footprint.

AEC-Q100 and 150°C junction rating

AEC-Q100 qualification covers the full automotive stress suite: high-temperature operating life, temperature cycling, moisture sensitivity, and ESD. The 150°C junction maximum extends the operating envelope beyond the typical 125°C grade, which is relevant for engine bay or exhaust-adjacent mounting where ambient temperatures push the silicon.

No last-time-buy or end-of-life notification has been issued. For dual-sourcing or a pin-compatible alternate, the TCAN1145DRQ1 is a same-family variant — verify the specific feature set (e.g., wake-up pattern or INH pin) against the application requirements.

Frequently asked questions

Does TCAN1144DRQ1 support CAN FD?

Yes, the 5 Mbps data rate rating confirms CAN FD support, enabling larger payloads and faster data phases beyond classical CAN.

What is the difference between TCAN1144DRQ1 and TCAN1145DRQ1?

Both are same-family automotive CAN FD transceivers. The key difference typically lies in the feature set — the TCAN1145DRQ1 may include additional wake-up pattern recognition or an INH (inhibit) output for system power management. Check the respective datasheets for the exact feature delta.

Is TCAN1144DRQ1 compatible with 5V microcontrollers?

No external level shifting is required for standard CAN controller connections.

Is TCAN1144DRQ1 obsolete?

No, TCAN1144DRQ1 carries an active product status. No end-of-life or last-time-buy notice has been issued.
