MAX33046ESHLD#

Overview

The MAX33046ESHLD is a development board designed for the MAX33046E half-duplex RS-485/RS-422 transceiver. The host IC operates on 3V to 5.5V supplies and supports data rates up to 20Mbps in an 8-pin SOIC package. It features ±40kV HBM ESD protection, ±25V fault protection, and true fail-safe receiver inputs. The board enables evaluation of high-speed communication performance within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides a hardware platform for evaluating the MAX33046E transceiver's signal integrity and power consumption.
• Facilitates testing of robustness against electrostatic discharge and bus short-circuit conditions.
• Supports verification of hot-swap capabilities and thermal shutdown behaviors during system integration.

Applications

• Programmable Controller
• Factory Automation Equipment
• Motion Controllers

Procurement Notes

Verify that the specific order references the MAX33046ESHLD evaluation kit rather than the standalone MAX33046E component. Confirm the revision status with the manufacturer, as availability may vary. Ensure the purchase includes all necessary documentation for proper setup and operation of the development environment.

Selection Notes

Select this board specifically for prototyping designs requiring the MAX33046E's 20Mbps speed capability. It is suitable for engineers needing to validate RS-485 network reliability under extreme environmental conditions before committing to mass production volumes.

Part Context

This development tool belongs to the MAX33045E/MAX33046E family of high-speed transceivers. While the MAX33045E is limited to 500kbps, the MAX33046E variant provides significantly higher throughput. This kit allows designers to compare performance characteristics between standard and high-speed industrial interface implementations.

Replacement Considerations

No direct substitute kits are documented. For functional replacement, consider the MAX33048E or MAX33049E series if full-duplex operation is required instead of the half-duplex architecture provided by the MAX33046E.

FAQ

What is the maximum data rate supported by the MAX33046E on this board?

The MAX33046E transceiver supports data rates up to 20Mbps.

Does the MAX33046E include protection against open or shorted receiver inputs?

Yes, it features a true fail-safe receiver that guarantees a logic-high output when inputs are open or shorted.

What is the ESD protection rating for the A and B lines?

The A and B lines provide ±40kV Human Body Model (HBM) protection per JEDEC standards.
