TJA1044GT/1Z

Drivers, Receivers, Transceivers Overview

The TJA1044GT/1Z is a high-speed CAN transceiver from the Mantis family, designed for automotive applications. It interfaces between a CAN protocol controller and the physical two-wire bus. Operating within a supply voltage range of 4.5 V to 5.5 V, it supports data rates up to 5 Mbit/s in Normal mode and features a low-current Standby mode with wake-up capability. The device includes undervoltage detection on VCC and VIO pins, overtemperature protection, and high ESD handling (8 kV IEC). It complies with ISO 11898-2:2024 and SAE J2284 standards.

Drivers, Receivers, Transceivers Feature Summary

• Supports very low-current Standby mode with local and bus wake-up capability
• Provides ideal passive behavior to the CAN bus when supply voltage is off
• Features excellent EMC performance without requiring a common mode choke
• Includes TXD dominant time-out functions and internal biasing for input pins

Drivers, Receivers, Transceivers Applications

• High-speed CAN networks in 12 V automotive systems
• Nodes requiring low-power modes with wake-up via the CAN bus
• CAN FD fast phase communication at data rates up to 5 Mbit/s

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and pin configuration. Ensure compatibility with system voltage requirements and interface standards before integration. Check for any product change notices or lifecycle status updates that may affect long-term availability.

Drivers, Receivers, Transceivers Selection Notes

Select this variant if the design requires a standard SOIC-8 package with a VIO pin for direct interfacing with 3.3 V to 5 V microcontrollers. Consider other variants like TJA1044B/C if shorter propagation delay is needed for larger network topologies. Verify that the application environment meets the specified temperature and voltage limits.

Drivers, Receivers, Transceivers Part Context

The TJA1044GT/1Z belongs to the Mantis family of high-speed CAN transceivers by NXP Semiconductors. This family offers significant improvements over previous generations, including enhanced EMC performance and optimized power management for automotive environments. The GT suffix indicates the inclusion of a VIO pin for flexible logic level interfacing.
