MAX33053EASA+

Overview

The MAX33053EASA+ is a +3.3V high-speed CAN transceiver in an 8-pin SOIC package, operating from -40°C to +125°C. It supports data rates up to 2Mbps with a VDD supply of 3.0V to 3.6V and a logic supply (VL) range of 1.62V to VDD. Key electrical parameters include ±65V fault protection on CANH/CANL, ±25kV ESD HBM protection, and a common mode input range of ±25V. The device features a Silent Mode pin (S), dominant timeout, short-circuit protection, and thermal shutdown.

Feature Summary

• Integrated robust protection including ±65V fault tolerance, ±25kV ESD HBM, and ±25V extended common mode range for noisy environments.
• Transmitter dominant timeout prevents bus lockup caused by controller errors or TXD faults.
• Silent Mode disables the transmitter while keeping the receiver active for monitoring applications.
• Logic-level supply input VL enables direct interfacing with low-voltage microcontrollers down to 1.62V.

Applications

• Programmable Logic Controllers
• Industrial Automation Systems
• Building Automation Networks
• Smart Grid Equipment
• Motor Control Applications

Procurement Notes

Verify the component against official Analog Devices datasheets to confirm pinout compatibility and RoHS compliance. Ensure the specific ordering suffix matches the required Silent Mode functionality. Cross-reference absolute maximum ratings with your system's power supply limits to prevent damage during installation.

Selection Notes

Select this part when harsh industrial environments require extended overvoltage protection and high noise immunity. The integrated logic level translator simplifies design by allowing direct connection to 1.8V or 3.3V controllers without external components. Consider the MAX33054E variant if standby mode or slow slew rate features are needed instead of silent mode.

Part Context

This component belongs to the MAX33053E/MAX33054E family of fault-protected CAN transceivers designed for DeviceNet and general CAN applications. It shares the same physical package and core protection architecture as its sibling parts, differing primarily in control pin configurations for standby versus silent operation modes.

Replacement Considerations

The MAX33054EASA+ is a functional alternative within the same family but replaces the Silent Mode pin with a Standby Mode pin. Verify that the application does not rely on the specific silent mode behavior before substituting.
