MAX33040EAKA+T

Overview

The MAX33040EAKA+T is a half-duplex CAN transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SOT-23 package. It operates on a supply voltage of 3.0V to 3.6V and supports data rates up to 5Mbps. The device features ±40V fault protection on CANH and CANL, ±40kV ESD HBM protection, and an input common-mode range of ±25V. It includes a shutdown pin and a multifunction standby pin for low-current standby mode or slow slew-rate operation. The operating temperature range is -40°C to +125°C.

Feature Summary

• Integrated ±40V fault tolerance on CANH and CANL lines for industrial robustness
• Transmitter dominant timeout mechanism prevents bus lockup from controller errors
• Multifunction STBY pin enables low-current standby mode or reduced EMI slow slew rate
• High ±40kV ESD Human Body Model protection on bus pins

Applications

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

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the part number corresponds to the lead-free/RoHS-compliant version as indicated by the '+' symbol. Ensure compatibility with the required 8-pin SOT-23 footprint during procurement planning.

Selection Notes

Select this component for applications requiring high-speed CAN communication at 5Mbps with extended fault protection capabilities. Consider the ±25V common-mode range for environments with significant ground potential differences between nodes. Evaluate the need for the standby mode's low current consumption versus the normal operational power requirements.

Part Context

This part belongs to the MAX33040E/MAX33041E family of +3.3V CAN transceivers designed for industrial applications. While the MAX33041E utilizes an SOIC package, the MAX33040E variant specifically offers SOT-23 and WLP options to save PCB area. Both variants share identical electrical characteristics and protection features.

Replacement Considerations

The MAX33040EAKA+ is the non-tape-and-reel equivalent of this component. For different package types within the same functional family, consider the MAX33040EAWA+ (WLP) or MAX33041EASA+ (SOIC). Verify pinout compatibility before substituting with other CAN transceivers.
