UJA1169ATK

The UJA1169ATK is a highly integrated automotive-grade transceiver IC designed by NXP Semiconductors for use in high-speed CAN (Controller Area Network) communication systems. It supports data rates up to 1 Mbps and complies with the ISO 11898-2 standard, making it suitable for robust vehicle networking applications. The device features a low-power operation mode, enabling efficient energy usage in battery-powered or electric vehicle environments. This transceiver includes advanced protection mechanisms such as electrostatic discharge (ESD) protection up to ±40 kV HBM, short-circuit protection, and overvoltage tolerance, ensuring reliable performance under harsh automotive conditions. Its wide supply voltage range of 3.0 V to 5.5 V allows compatibility with various power systems found in modern vehicles. Additionally, the UJA1169ATK incorporates a built-in wake-up function that enables low-power standby modes while maintaining network responsiveness—an essential feature for always-on vehicle systems. The IC offers excellent electromagnetic compatibility (EMC) performance, meeting stringent automotive EMC standards like CISPR 25 Class 5. It also provides high noise immunity and signal integrity, which are critical for maintaining communication reliability in electrically noisy environments such as engine compartments or near motor controllers. The transceiver supports both single-ended and differential signaling, enhancing flexibility in system design. Designed for integration into advanced driver-assistance systems (ADAS), infotainment units, body control modules, and powertrain systems, the UJA1169ATK facilitates seamless communication between electronic control units (ECUs). Its compact footprint and minimal external component requirements simplify PCB layout and reduce overall system cost. The device operates reliably across an extended temperature range from -40°C to +125°C, making it ideal for extreme environmental conditions encountered in automotive applications. In summary, the UJA1169ATK combines high performance, robust protection, and energy efficiency in a single package, offering a reliable solution for next-generation automotive communication networks.
