MAX13054ESA+T

Drivers, Receivers, Transceivers Overview

The MAX13054ESA+T is an industry-standard high-speed CAN transceiver featuring ±80V fault protection on the bus lines. It operates with a +5V supply (VCC) and includes a dedicated VCC2 logic supply input for direct compatibility with +3.3V microcontrollers. The device supports data rates up to 1Mbps and provides ±8kV ESD protection per IEC 61000-4-2 contact discharge standards. It incorporates a dominant timeout function, thermal shutdown, and short-circuit protection. The component is housed in an 8-pin SO package and is specified for operation across temperature ranges of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides extended ±80V fault protection on CANH and CANL pins for harsh industrial environments.
• Features a separate VCC2 logic supply pin enabling full compatibility with +3.3V logic systems while operating from a +5V main supply.
• Includes a transmit dominant timeout function that disables the transmitter if the TXD input remains low for longer than 1ms.
• Offers ±8kV ESD protection on bus inputs according to IEC 61000-4-2 contact discharge testing.

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes
• Medium- and heavy-duty truck systems
• Industrial network applications requiring overvoltage protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESA+' against the manufacturer's current ordering information to confirm the -40°C to +85°C temperature range and lead-free status. Ensure the VCC2 pin is correctly connected to the microcontroller's logic voltage level to maintain signal integrity. Confirm package availability matches the 8-pin SO outline number S8M+5 required for the PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing a +5V CAN controller with a +3.3V microcontroller without external level shifters. Choose this part over other family members specifically for its dedicated VCC2 pin; models like the MAX13050 lack this feature. Consider the MAX13052 only if slope-control mode is required for EMI reduction at lower speeds. Verify that the ±80V fault protection meets the system's electrical stress requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1305x family of high-speed CAN transceivers designed for robust industrial communication. While sharing pinouts and core functionality with the MAX13050, MAX13052, and MAX13053, the MAX13054 is distinct due to its dual-supply architecture. This allows it to bridge voltage domains between 5V bus controllers and 3.3V processing units, simplifying system design in mixed-voltage automotive and industrial networks.

Drivers, Receivers, Transceivers Replacement Considerations

Public datasheets list TLE6250v33 and CF163 as pin-for-pin replacements for the MAX13054. Verify functional equivalence regarding the VCC2 logic interface and fault protection ratings before substitution.

Drivers, Receivers, Transceivers FAQ

How does the MAX13054 handle logic level translation?

It uses a dedicated VCC2 pin to power the digital I/O interface, allowing direct connection to +3.3V microcontrollers while the main driver circuit operates from a +5V supply.

What happens if the TXD input is held low for too long?

The dominant timeout function disables the transmitter after approximately 1ms, forcing the bus into a recessive state to prevent bus locking by a faulty controller.

Is the MAX13054 compatible with the ISO11898 standard?

Yes, the device is fully compatible with the ISO11898 standard for high-speed CAN transceivers.
