MAX3051ESA+T

Overview

The MAX3051ESA+T is a +3.3V single-supply CAN transceiver designed for nonautomotive applications. It supports data rates up to 1Mbps in high-speed mode and offers slope-control mode for EMI reduction at speeds up to 500kbps. The device operates within an extended temperature range of -40°C to +85°C and features a wide common-mode input range from -7V to +12V. Supply current is 35mA in dominant state, 2mA in recessive state, 8µA in standby, and less than 1µA in shutdown. It includes thermal shutdown protection above +160°C and ±12kV HBM ESD protection.

Feature Summary

• Four operating modes including high-speed, slope-control, standby, and shutdown for optimized performance and power consumption
• Wide common-mode range exceeding ISO 11898 specifications (-7V to +12V) suitable for harsh environments
• Programmable slew-rate limiting via external resistor to reduce EMI effects on unshielded cables
• Robust protection features including thermal shutdown and output short-circuit current limiting

Applications

• Industrial control and networks
• Telecom backplane systems
• Printers and JetLink devices
• Consumer applications

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official documentation. Confirm the package type matches the SO-8 specification. Ensure the ordering suffix corresponds to the lead-free RoHS-compliant version as indicated by the plus sign in the part number.

Selection Notes

Select this transceiver for 3.3V microcontroller interfaces where automotive-grade fault protection is not required. Use the slope-control mode when connecting to unshielded twisted pair or parallel cables to minimize electromagnetic interference. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range.

Part Context

The MAX3051 belongs to the Maxim Integrated CAN transceiver family, specifically designed for low-power, nonautomotive uses. It serves as an interface between CAN protocol controllers and physical bus lines, offering a cost-effective alternative to automotive-standard transceivers while maintaining essential communication capabilities.
