MAX3053ESA+T

Overview

The MAX3053ESA+T is a CAN transceiver designed for industrial systems, supporting data rates up to 2Mbps. It features ±80V fault protection against shorts to high-voltage power buses and operates from a single +5V supply. The device includes three modes: high-speed, slope control (40kbps to 500kbps), and shutdown with 15μA current consumption. An autoshutdown function activates after 47ms of inactivity. It is housed in an 8-pin SO package and specified for operation between -40°C and +85°C.

Procurement Notes

Verify the component's authenticity by checking the manufacturer markings and datasheet revision history. Confirm the specific suffix matches the required temperature range and packaging specifications. Ensure compliance with relevant industry standards before integration into final designs.

Selection Notes

Select this component for applications requiring robust fault protection against high-voltage bus shorts. Consider the slope control mode for EMI-sensitive environments using unshielded cables. Verify that the system operates within the specified voltage and temperature limits for optimal performance.

Part Context

This part belongs to the MAX3053 family of CAN transceivers manufactured by Analog Devices Inc./Maxim Integrated. It is specifically designed for industrial applications where high reliability and fault tolerance are critical. The device interfaces between the CAN protocol controller and the physical bus lines.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Ensure any substitute supports the required ±80V fault protection and data rate specifications. Verify thermal and electrical characteristics match the original design requirements.

FAQ

What is the purpose of the RS pin?

The RS pin selects the operating mode. Connecting it to ground enables high-speed mode, while connecting a resistor allows slope control mode to reduce EMI.

How does the autoshutdown function work?

The device enters a low-current shutdown mode if the bus or CAN controller remains inactive for 47ms or longer, automatically waking up when activity resumes.

What is the maximum data rate supported?

The MAX3053ESA+T supports data rates up to 2Mbps in high-speed mode.
