High-speed CAN transceiver with Standby mode
Rev. 1 — 2 March 2018
Product data sheet
1. General description
The TJA1044V is part of the Mantis family of high-speed CAN transceivers. It provides an
interface between a Controller Area Network (CAN) protocol controller and the physical
two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the
automotive industry, providing the differential transmit and receive capability to (a
microcontroller with) a CAN protocol controller.
The TJA1044V offers a feature set optimized for 12 V automotive applications, with
significant improvements over NXP's first- and second-generation CAN transceivers, such
as the TJA1040 and TJA1042, and excellent ElectroMagnetic Compatibility (EMC)
performance. Additionally, the TJA1044V features:
Ideal passive behavior to the CAN bus when the supply voltage is off
A very low-current Standby mode with bus wake-up capability
Excellent EMC performance at speeds up to 500 kbit/s, even without a common mode
choke
TJA1044VT/3 and TJA1044VTK/3 can be interfaced directly to microcontrollers with
supply voltages from 3 V to 5 V
These features make the TJA1044V an excellent choice for all types of HS-CAN
networks, in nodes that require a low-power mode with wake-up capability via the CAN
bus.
The TJA1044V implements the CAN physical layer as defined in ISO 11898-2:2016 and
SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the
CAN FD fast phase at data rates up to 5 Mbit/s.

VIO input on TJA1044Vx/3 variants allows for direct interfacing with 3 V to 5 V
microcontrollers. Variants without a VIO pin can interface with 3.3 V and 5 V-supplied
microcontrollers, provided the microcontroller I/Os are 5 V tolerant.
Both VIO and non-VIO variants are available in SO8 and leadless HVSON8 (3.0
mm 3.0 mm) packages; HVSON8 with improved Automated Optical Inspection (AOI)
capability.
2.2 Predictable and fail-safe behavior
Functional behavior predictable under all supply conditions
Transceiver disengages from bus when not powered (zero load)
Transmit Data (TXD) and bus dominant time-out functions
Internal biasing of TXD and STB input pins
2.3 Protection
High ESD handling capability on the bus pins (8 kV IEC and HBM)
Bus pins protected against transients in automotive environments
Undervoltage detection on pins VCC and VIO
Thermally protected
2.4 TJA1044V CAN FD
Timing guaranteed for CAN FD data rates up to 5 Mbit/s
Improved TXD to RXD propagation delay of 210 ns
