ATA6570

The ATA6570 is a high-performance CAN transceiver manufactured by Microchip Technology, designed for robust and reliable communication in automotive and industrial applications. It supports the ISO 11898-2 standard for high-speed CAN networks, enabling data rates up to 1 Mbit/s. The device features a wide supply voltage range from 3.0 V to 5.5 V, ensuring compatibility with various power systems commonly found in modern vehicles and embedded systems. One of its key characteristics is its excellent electromagnetic compatibility (EMC) performance, which includes high immunity to electrostatic discharge (ESD), fast transient bursts, and radiated emissions. This makes it ideal for use in electrically noisy environments such as those found in automotive engine compartments or industrial machinery. The ATA6570 also incorporates integrated protection features like overvoltage and short-circuit protection on both the CANH and CANL lines, enhancing system reliability and reducing the need for external components. The transceiver operates in two modes: normal and low-power sleep mode. In sleep mode, the quiescent current drops to less than 1 µA, significantly reducing power consumption during idle periods—an essential feature for energy-efficient designs in battery-powered or always-on systems. Additionally, the device supports hot-plug functionality, allowing safe connection and disconnection without damaging the circuitry, which simplifies maintenance and diagnostics in complex systems. It is commonly used in automotive control units such as ECUs for engine management, transmission control, and body electronics. Beyond automotive applications, the ATA6570 is suitable for industrial automation, medical devices, and any application requiring resilient serial communication over CAN buses. Its ability to maintain signal integrity under harsh conditions ensures stable operation even in extreme temperatures ranging from –40°C to +125°C. The ATA6570 offers an optimized layout for PCB design, minimizing trace length and parasitic effects. It is available in a compact SO8 package, making it ideal for space-constrained designs. With its combination of high-speed capability, low power consumption, and robust protection mechanisms, the ATA6570 provides a reliable interface solution for demanding communication protocols in safety-critical and high-reliability environments.
