UJA1169TK/F/3Z

Specialized Overview

The UJA1169TK/F/3Z is a mini high-speed CAN System Basis Chip (SBC) from NXP Semiconductors. It integrates an ISO 11898-2:201x compliant HS-CAN transceiver supporting active CAN FD communication up to 2 Mbit/s, and a scalable 3.3 V 250 mA low-drop voltage regulator (V1) for microcontroller supply. The device features a watchdog timer, SPI interface, and partial networking capabilities per ISO 11898-6:2013 with CAN FD-passive support. It operates in Standby and Sleep modes with very low current consumption and includes overtemperature warning/shutdown. The component is housed in a leadless HVSON20 package (SOT1360-1).

Specialized Feature Summary

• Integrates a high-speed CAN transceiver with active CAN FD support up to 2 Mbit/s.
• Includes a scalable 3.3 V 250 mA low-drop voltage regulator for the host microcontroller.
• Supports partial networking with selective wake-up and CAN FD-passive functionality.
• Features autonomous bus biasing and robust ESD protection on CAN-bus pins.

Specialized Applications

• Automotive electronic control units requiring high-speed CAN connectivity.
• Battery management systems in electric vehicles.
• Body control modules and gateway nodes in automotive networks.

Specialized Procurement Notes

Verify the specific ordering suffix 'Z' against the manufacturer's official documentation to confirm packaging details such as reel or tape specifications. Ensure the component meets the required automotive qualification standards for your specific application environment before finalizing procurement.

Specialized Selection Notes

Select this variant when a 3.3 V microcontroller supply is required alongside high-speed CAN communication. The '/F' suffix indicates support for partial networking and CAN FD-passive, which is essential for mixed classic CAN and CAN FD networks. Verify that the external PNP transistor configuration aligns with the thermal scaling requirements of the design.

Specialized Part Context

The UJA1169 series comprises six variants designed for automotive applications. The UJA1169TK/F/3Z belongs to the family featuring a 3.3 V main regulator (V1), dedicated CAN supply (V2), and partial networking capabilities. It is part of NXP's portfolio of system basis chips aimed at reducing component count and improving power management in vehicle electronics.

Specialized Replacement Considerations

Direct substitutes within the same family include UJA1169TK/F (5 V V1) or UJA1169TK/3 (3.3 V V1 without partial networking). Cross-family replacements require careful evaluation of pin compatibility and regulator specifications.
