MAX33041EASA+T

Overview

The MAX33041EASA+T is a +3.3V high-speed CAN transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SOIC package. It supports data rates up to 5Mbps and operates within a supply voltage range of 3.0V to 3.6V. The device provides ±40V fault protection on CANH and CANL lines, along with ±40kV ESD Human Body Model (HBM) protection. It features an extended common-mode input range of ±25V and includes a shutdown pin for low current consumption. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• Integrated ±40V fault tolerance on CANH and CANL lines for industrial robustness
• High ±40kV ESD HBM protection capability on bus lines
• Extended ±25V common-mode input range exceeding standard ISO 11898-2 specifications
• Transmitter dominant timeout mechanism to prevent bus lockup

Applications

• Industrial Equipment
• Instrumentation
• Motor Control
• Building Automation
• Industrial Drone

Procurement Notes

Verify the specific ordering suffix '+T' corresponds to tape-and-reel packaging when sourcing components. Confirm that the 'E' designation indicates the extended temperature range suitable for harsh environments. Ensure compatibility with 3.3V logic interfaces and validate that the 8-pin SOIC footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high noise immunity and overvoltage protection on CAN networks. The extended common-mode range makes it suitable for systems with significant ground potential differences. Consider the standby mode functionality if power conservation during idle periods is a priority. Verify that the 5Mbps speed meets the network latency requirements.

Part Context

This part belongs to the MAX33040E/MAX33041E family of +3.3V CAN transceivers. While the MAX33040E is available in SOT23 and WLP packages, the MAX33041E specifically utilizes the 8-pin SOIC package. Both share identical electrical characteristics and protection features, differing primarily in physical form factor to accommodate various board space constraints.

Replacement Considerations

The MAX33040E serves as a functional equivalent within the same family, offering identical electrical performance but available in different package styles such as SOT23 or WLP. Direct pin-to-pin replacement is possible only if the target application accommodates the alternative package dimensions.
