UJA1169LTK/FZ

Specialized Overview

The UJA1169LTK/X/FZ is a mini high-speed CAN companion System Basis Chip (SBC) from NXP Semiconductors. It integrates an ISO 11898-2:201x compliant HS-CAN transceiver supporting CAN FD active communication up to 2 Mbit/s, and a scalable 5 V 250 mA low-drop voltage regulator (V1). This variant includes a protected off-board sensor supply (VEXT) for external components. It features autonomous bus biasing, very low quiescent current in Standby and Sleep modes, and supports partial networking with selective wake-up and CAN FD-passive functionality.

Specialized Feature Summary

• Integrates a high-speed CAN transceiver with CAN FD support and autonomous bus biasing
• Includes a dedicated short-circuit proof off-board sensor supply (VEXT)
• Supports partial networking with selective wake-up and CAN FD-passive capability
• Features a watchdog with multiple operating modes and configurable limp-home output

Specialized Applications

• Automotive applications requiring multiple transceivers or additional power resources
• Secondary SBC configurations where interface supply domain adaptation is necessary
• Networks supporting both CAN FD and classic CAN communications

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and feature set. Confirm that the component meets all required automotive standards and environmental specifications for the intended application before finalizing procurement decisions.

Specialized Selection Notes

Select this variant when an off-board sensor supply is required instead of an on-board CAN supply. Ensure the design accommodates the HVSON20 package thermal requirements and utilizes the VIO pin for proper microcontroller interfacing across different supply domains.

Specialized Part Context

This component belongs to the UJA1169 product series designed as companion chips for main system basis chips. The UJA1169L family offers variants with either on-board CAN supplies or off-board sensor supplies, providing flexibility for scaling automotive networks with additional loads or transceivers.

Specialized Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the UJA1169 family. Verify compatibility regarding supply configurations and partial networking support before considering alternative devices.
