MAX3053ASA+T

Overview

The MAX3053ASA+T is a CAN transceiver designed for industrial systems requiring data rates up to 2Mbps. It features ±80V fault protection against shorts to high-voltage power buses, ensuring robust operation in harsh environments. The device supports three operating modes: high-speed operation up to 2Mbps, slope control mode to reduce EMI (40kbps to 500kbps), and a low-current shutdown mode consuming only 15μA. It includes automatic wakeup from shutdown, thermal shutdown, and current limiting capabilities. The component is fully compatible with the ISO 11898 standard and interfaces between the CAN protocol controller and physical bus lines.

Feature Summary

• Provides ±80V fault protection against shorts to high-voltage power buses
• Supports high-speed operation up to 2Mbps and slope control mode to reduce EMI
• Features 15μA low-current shutdown mode with automatic wakeup capability

Applications

• Industrial Control and Networks
• Printers
• HVAC Controls
• Telecom 72V Systems

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the ordering part number matches the exact package type required for your PCB layout. Cross-reference the datasheet revision date to confirm feature consistency.

Selection Notes

Select this component for applications requiring high voltage fault tolerance on CAN bus lines. Consider the slope control mode if electromagnetic interference reduction is critical within the 40kbps to 500kbps range. Evaluate the 15μA shutdown current for battery-powered systems where standby power consumption must be minimized. Verify compatibility with existing CAN controllers supporting ISO 11898 standards.

Part Context

The MAX3053 belongs to Maxim Integrated's family of fault-protected CAN transceivers. It shares functional similarities with the MAX3050 but offers enhanced fault protection ratings. The 'ASA' designation typically denotes an automotive-grade temperature range and SOIC-8 package. The '+T' suffix specifies reel packaging for automated assembly processes.

Replacement Considerations

The MAX3050ASA+T is a similar transceiver within the same product family. Verify if the specific fault protection levels and operating modes meet your design requirements before substitution. Check pinout compatibility and electrical parameter overlaps to ensure seamless integration without circuit redesign.
