MAX13053ASA

Drivers, Receivers, Transceivers Overview

The MAX13053ASA is a +5V 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 range of 4.5V to 5.5V 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) to disable the transmitter while keeping the receiver active. Supply currents are typically 5mA in dominant mode and 4mA in recessive mode at no load.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±65V fault tolerance for CANH and CANL lines to withstand overvoltage conditions.
• Silent-mode capability via the S pin allows disabling the transmitter while maintaining bus monitoring.
• Extended common mode input range of ±25V exceeds standard ISO11898 specifications for noisy environments.
• Transmitter dominant timeout prevents bus lockup caused by controller errors or stuck TXD inputs.

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current ordering information to confirm the exact temperature grade and RoHS compliance status. Ensure the silent-mode variant matches the design requirement rather than the standby-mode alternative. Cross-reference the datasheet revision date to confirm the validity of the electrical characteristics provided.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed CAN communication up to 2Mbps is required alongside robust fault protection. The separate VL pin enables compatibility with microcontrollers ranging from 1.62V to 5.5V without external level shifters. Choose this part over the MAX13054A if silent-mode operation is preferred over standby-mode functionality for power management.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13053A/MAX13054A family of industrial CAN transceivers. It shares the same core architecture as the MAX13054A but replaces the STBY pin with an S pin to enable silent-mode operation. Both variants offer identical fault protection and speed capabilities within the 8-pin SOIC package.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13054AEASA+ serves as a functional substitute if standby-mode operation is acceptable instead of silent-mode. Verify that the replacement part's pinout and electrical characteristics align with the existing circuit design before implementation.

Drivers, Receivers, Transceivers FAQ

How does the silent-mode feature function?

Driving the S pin high disables the transmitter regardless of the TXD input level, while the receiver remains active to monitor the bus line.

What is the purpose of the dominant timeout?

The dominant timeout releases the bus to a recessive state if the TXD input remains low for longer than approximately 2.5ms, preventing bus lockup from controller errors.

Can this transceiver interface with 3.3V logic?

Yes, the separate VL pin allows the device to interface with logic systems down to 1.62V, making it compatible with 3.3V microcontrollers.
