MAX33011EASA+T

Overview

The MAX33011EASA+T is a +5V, high-speed CAN transceiver from the MAX3301xE family, designed for industrial applications requiring robust fault protection. It supports data rates up to 5Mbps and operates over an extended temperature range of -40°C to +125°C. The device features ±65V fault tolerance on the CANH and CANL lines, ±45kV ESD HBM protection, and an input common-mode range (CMR) of ±25V. It incorporates integrated fault detection and reporting capabilities, monitoring for overcurrent, overvoltage, and transmission failures via a dedicated FAULT pin. The component utilizes an 8-pin SOIC package and includes a Silent Mode feature to disable the transmitter while keeping the receiver active.

Feature Summary

• Integrated ±65V fault protection on CAN bus lines with ±45kV ESD HBM rating
• Fault detection and reporting mechanism for overcurrent, overvoltage, and transmission failure
• Silent Mode capability to disable the transmitter independently of the TXD input
• Extended common-mode input range of ±25V for noisy environments

Applications

• Industrial Automation
• Building Automation
• Heavy Equipment/Machinery

Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape-and-reel packaging format as specified in the manufacturer's documentation. Confirm the presence of the '+' suffix indicates RoHS compliance and lead-free status. Ensure the specific variant matches the required feature set, such as the inclusion of the Silent Mode pin configuration unique to this model within the family.

Selection Notes

Select this component when designing systems that require high-voltage fault tolerance up to ±65V on the CAN bus. It is suitable for applications needing explicit fault reporting to the local controller to reduce downtime. Consider this part if the design requires a separate logic supply or low-voltage compatibility, although these are primarily features of other variants in the series; verify VL pin requirements against the specific microcontroller interface.

Part Context

This device belongs to the MAX3301xE family of +5V CAN transceivers manufactured by Analog Devices Inc./Maxim Integrated. The family shares core specifications regarding fault protection and data rates but varies in package type and control features. While the MAX33012E offers Standby mode, the MAX33011E specifically provides Silent Mode functionality.

Replacement Considerations

Direct functional substitutes within the same family include the MAX33012EASA+, which replaces Silent Mode with Standby Mode. Other family members like the MAX33014E and MAX33015E utilize different packages and additional features such as Loopback mode.
