Maxim Integrated MAX13021ASA+T Automotive-Grade CAN Transceiver

The MAX13021ASA+T from Maxim Integrated is a high-performance, automotive-grade Controller Area Network (CAN) transceiver that facilitates reliable communication in vehicle networking applications. Designed to interface between a CAN protocol controller and the physical two-wire CAN bus, this transceiver is optimized for high-speed operations in harsh automotive environments.

This robust transceiver is compliant with the ISO 11898 standard, ensuring compatibility with industry-standard CAN protocols. It operates over a wide temperature range of -40°C to +125°C, making it suitable for various automotive applications, including powertrain, chassis, and body electronics.

The MAX13021ASA+T features a slew rate control for reduced electromagnetic emissions, which is essential for meeting stringent automotive EMI requirements. Additionally, it offers protection against transients, enhancing its resilience to the electrical disturbances commonly encountered in automotive settings. This includes features such as short-circuit protection, thermal shutdown, and loss-of-ground and overvoltage protection, ensuring reliable operation under adverse conditions.

This transceiver is available in a compact 8-pin SOIC package, making it an excellent choice for space-constrained applications. Its small footprint is complemented by a low-current standby mode, which helps to minimize power consumption when the network is idle, contributing to the overall energy efficiency of the vehicle's electronic systems.

The MAX13021ASA+T supports a wide supply voltage range of 4.5V to 5.5V, and it is capable of transmitting and receiving at CAN bus speeds of up to 1 Mbps. Its dominant time-out function prevents the bus line from being driven indefinitely in the event of a fault, thereby safeguarding network integrity.

With its combination of high-speed operation, robust protection features, and compliance with automotive standards, the Maxim Integrated MAX13021ASA+T is an ideal solution for designers looking to implement reliable CAN communication in their automotive applications.
