ATA6562

The ATA6562 is a high-performance CAN transceiver designed by Microchip Technology for robust and reliable communication in automotive and industrial applications. It supports the ISO 11898-2 standard for high-speed CAN (Controller Area Network) protocols, enabling data transmission rates up to 1 Mbps. The device operates over a wide supply voltage range of 3.0 V to 5.5 V, making it suitable for various power systems found in modern vehicles and embedded systems. This transceiver features integrated protection mechanisms, including electrostatic discharge (ESD) protection up to ±8 kV (Human Body Model), short-circuit protection, and thermal shutdown functionality. These safeguards ensure long-term reliability even under harsh environmental conditions such as electromagnetic interference (EMI) or transient voltage spikes commonly encountered in automotive environments. The ATA6562 provides differential signaling with a low propagation delay, ensuring minimal signal distortion and precise timing for critical real-time communications. Its low quiescent current consumption—typically less than 3 mA in active mode—contributes to energy efficiency, which is essential for battery-powered or fuel-efficient vehicle designs. Additionally, the transceiver includes a wake-up function that allows the node to transition from sleep to active mode quickly upon detecting a valid CAN message, further optimizing power management. Designed for operation in extreme temperatures, the ATA6562 functions reliably across a -40°C to +125°C ambient temperature range, meeting the stringent requirements of automotive-grade components. It also offers excellent noise immunity and common-mode rejection, enhancing signal integrity in electrically noisy environments like engine compartments or industrial machinery. Applications include engine control units (ECUs), body control modules, powertrain systems, telematics, and industrial automation where high-speed, fault-tolerant communication is required. The device’s compatibility with standard CAN controllers and its robust electrical characteristics make it an ideal choice for implementing secure and efficient communication networks in safety-critical systems. In summary, the ATA6562 combines performance, durability, and low power consumption in a single package, delivering a cost-effective solution for high-reliability CAN-based communication in demanding environments.
