MAX3053ASA+

Overview

The MAX3053ASA+ is a ±80V fault-protected, high-speed CAN transceiver designed for industrial systems requiring data rates up to 2Mbps. It operates from a single +5V supply with typical dominant and recessive supply currents of 56mA and 3.6mA respectively. The device features three operating modes: high-speed, slope control (40kbps to 500kbps), and shutdown (15μA). It includes autoshutdown after 47ms of inactivity, thermal shutdown at 160°C, and current limiting. The component is specified for an extended temperature range of -40°C to +125°C and is housed in an 8-pin SO package.

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 automatic shutdown when the bus or controller is inactive for 47ms or greater
• Fully compatible with the ISO 11898 standard

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm RoHS compliance status, as indicated by the datasheet documentation. Ensure that the selected variant matches the required operating temperature range for your application environment. Cross-reference the manufacturer's official documentation to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select the MAX3053ASA+ when an extended industrial temperature range of -40°C to +125°C is required. Choose this model over the MAX3053ESA+ if operation beyond +85°C is necessary. Utilize the RS pin configuration to enable slope control mode for applications requiring reduced electromagnetic interference on unshielded cables.

Part Context

The MAX3053ASA+ belongs to the MAX3053 family of CAN transceivers manufactured by Analog Devices / Maxim Integrated. This series provides robust fault protection and low supply current characteristics suitable for demanding industrial environments. The 'ASA+' designation specifically denotes the extended temperature grade and lead-free packaging compliant with environmental standards.

Replacement Considerations

The MAX3053ESA+ serves as a direct functional substitute within the same package but is rated for a commercial temperature range of -40°C to +85°C.
