What are the key features of TCAN1044ADRQ1?
- Automotive AEC-Q100-qualified CAN transceiver with standby mode reduces quiescent current for energy-efficient network nodes
- Supports CAN data rates up to 8 Mbps enabling both Classic CAN and CAN FD protocol operation on a single device
- IEC 61000-4-2 Level 4 ESD protection on CANH and CANL wrt GND guards bus pins against high-voltage discharge events in harsh automotive environments
What is TCAN1044ADRQ1 used for?
The TCAN1044ADRQ1 is used in automotive body control modules, powertrain ECUs, and ADAS sensor nodes where a robust AEC-Q100-qualified CAN physical-layer interface is required to connect microcontrollers to the vehicle's CAN bus at up to 8 Mbps. Its low-power standby mode makes it well suited for gateway ECUs and always-on modules that must wake from standby on a remote CAN frame while minimizing battery drain. The device is also deployed in industrial motor-drive and off-highway vehicle networks where the IEC 61000-4-2 ESD rating ensures reliable operation in high-interference electrical environments.

Frequently Asked Questions
What data rate does the TCAN1044ADRQ1 support, and does it handle both Classic CAN and CAN FD frames?
The TCAN1044ADRQ1 supports CAN bus data rates up to 8 Mbps, which covers the full speed range of Classic CAN (up to 1 Mbps) and CAN FD data-phase rates used in modern automotive ECUs. This single-device flexibility allows a design to support both legacy and next-generation CAN FD nodes on the same PCB without swapping transceivers, reducing bill-of-materials complexity in mixed-protocol vehicle networks.
How does the standby mode of the TCAN1044ADRQ1 reduce battery drain in always-on automotive modules?
In standby mode the TCAN1044ADRQ1 reduces its supply current to microampere-level quiescent draw while continuing to monitor the CANH and CANL lines for a remote wake-up pattern. When a valid dominant edge is detected, the device asserts a wake output to the host microcontroller, allowing the system to re-enter normal operation within microseconds. This behavior meets ISO 11898-2 wake-up requirements and is essential for body control modules that must remain in a low-power state for hours while parked.
What ESD protection level does the TCAN1044ADRQ1 provide on its CAN bus pins, and why is this important for harsh automotive wiring harnesses?
The TCAN1044ADRQ1 provides IEC 61000-4-2 Level 4 ESD protection on both CANH and CANL pins referenced to GND, which corresponds to a ±8 kV contact discharge rating. This level of protection is critical for automotive wiring harness environments where technician handling, electrostatic discharge from connectors, and load-dump transients can inject high-voltage pulses onto the bus lines. The 8-pin SOIC package keeps the protected transceiver compact enough for integration directly at the ECU connector without external TVS diodes.
