MAX3058ASA+

Overview

The MAX3058ASA+ is a high-speed CAN transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed to interface between the controller area network protocol controller and the physical bus lines. It operates from a single +5V supply with a voltage range of 4.5V to 5.5V. The device supports data rates up to 1Mbps in high-speed mode and features slope control for reduced EMI at rates up to 500kbps. It includes thermal shutdown, current limiting, and ±12kV human body model ESD protection. The component is housed in an 8-pin SO package and is specified over an operating temperature range of -40°C to +125°C.

Feature Summary

• Four distinct operating modes including high-speed, slope-control, standby, and shutdown capabilities
• Integrated thermal shutdown and output short-circuit current limiting for enhanced reliability
• Robust electrostatic discharge protection rated at ±12kV via the human body model
• Slope-control functionality allows optimization of slew rates to minimize electromagnetic interference

Applications

• Printer systems
• Telecom backplane networks
• Industrial control networks
• JetLink applications

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure compatibility with system voltage requirements and communication protocols before integration. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Selection Notes

Select this component when designing CAN interfaces requiring operation up to 1Mbps with low supply current consumption. The MAX3058ASA+ is suitable for environments needing extended temperature ranges and robust ESD protection. Consider the standby mode feature for power-sensitive applications where receiver activity must be maintained while transmitters are inactive.

Part Context

This device belongs to the MAX3058/MAX3059 family of 5V, 1Mbps, low supply current CAN transceivers. It serves as a physical layer interface for Controller Area Network protocols, providing differential transmit and receive capabilities. The series is primarily targeted at printer and telecom backplane applications requiring reliable data transmission.

Replacement Considerations

The MAX3059ASA+ is a related variant within the same family but lacks the standby mode and internal termination resistor found in other configurations. Verify functional equivalence regarding pinout and electrical characteristics before substitution.

FAQ
