TJA1448AT/0Z

Drivers, Receivers, Transceivers Overview

The TJA1448AT/0Z is a dual high-speed CAN transceiver from the TJA144x family, designed for automotive applications. It provides an interface between a CAN or CAN FD protocol controller and the physical two-wire bus. Qualified to AEC-Q100 Grade 1, it supports data rates up to 5 Mbit/s in the CAN FD fast phase. The device operates within a VCC supply range of 4.5 V to 5.5 V and features Normal and Standby modes controlled independently via STB pins. It includes undervoltage detection, internal biasing for fail-safe behavior, and protection against ESD (8 kV IEC) and overtemperature conditions.

Drivers, Receivers, Transceivers Feature Summary

• Dual independent channels with Normal and Standby operating modes
• Low-power management with host and bus wake-up capability
• Fail-safe behavior defined by internal biasing and undervoltage detection
• High ESD handling capability on bus pins

Drivers, Receivers, Transceivers Applications

• Automotive CAN network interfaces
• CAN FD fast phase communication systems
• Gateway applications requiring low standby current

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'T' indicates the SO14 package type as documented in the official NXP datasheet. Confirm that the component meets AEC-Q100 Grade 1 qualification requirements for your specific application environment. Ensure compatibility with ISO 11898-2:2016 standards before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a dual-channel solution with independent mode control is required. The AT suffix denotes the SO14 package, suitable for standard surface mount assembly. Consider the TJA1448BT/0Z if the HVSON14 package is preferred for thermal performance or space constraints. Verify voltage level compatibility with the connected microcontroller logic levels.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TJA144x family of high-speed CAN transceivers. It serves as a pin-compatible replacement for legacy devices like the TJA1059, allowing for easy retrofitting into existing designs without hardware changes. The family offers variants with different packages and features such as VIO pins for 3.3V interfacing.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1448A/B/C series are pin-compatible replacements for the TJA1059. For package-specific substitutions, compare the TJA1448AT/0Z (SO14) with the TJA1448BT/0Z (HVSON14). Ensure the replacement maintains the required AEC-Q100 Grade 1 qualification.
