MAX13054ESA-T

Drivers, Receivers, Transceivers Overview

The MAX13054ESA-T is a high-speed CAN transceiver from the MAX1305x series, designed for automotive and industrial networks. It features ±80V fault protection on CANH/CANL pins and ±8kV ESD protection per IEC 61000-4-2. The device supports data rates up to 1Mbps and includes a dedicated VCC2 logic supply pin for +3.3V microcontroller interfacing while operating from a +5V main supply. Key protections include thermal shutdown, short-circuit current limiting, and a dominant timeout function that disables the transmitter if TXD remains low for over 1ms. It operates within -40°C to +125°C temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Provides extended ±80V fault protection on bus lines for harsh environments
• Features a separate VCC2 logic supply pin enabling direct +3.3V microcontroller interface
• Includes dominant timeout functionality to prevent bus locking by hung controllers
• Offers ±8kV ESD protection compliant with IEC 61000-4-2 contact discharge standards

Drivers, Receivers, Transceivers Applications

• +12V and +42V battery automotive systems
• DeviceNet nodes
• Medium- and heavy-duty truck systems
• Industrial network applications requiring overvoltage protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the specific temperature grade matches the application requirements, as the 'E' suffix denotes the -40°C to +85°C range while 'A' variants support up to +125°C. Ensure the component source provides valid traceability documentation to guarantee authenticity and compliance with RoHS standards.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX13054 specifically when a separate logic supply voltage is required to interface with 3.3V controllers without level shifting. This model is distinct from the MAX13050/52 which utilize a SPLIT pin for common-mode stabilization. Designers should ensure the system operates within the specified VCC2 range of 3V to 3.6V to maintain proper logic compatibility and signal integrity.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1305x family of industry-standard high-speed CAN transceivers. It shares pinout compatibility with the MAX13050, MAX13052, and MAX13053 models, facilitating board-level upgrades or design variations. Unlike other family members, it lacks slope-control or silent modes but uniquely offers independent logic power supply flexibility.

Drivers, Receivers, Transceivers Replacement Considerations

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

Drivers, Receivers, Transceivers FAQ

How does the MAX13054 handle a continuous low signal on the TXD input?

The device features a transmit dominant timeout function. If the TXD input remains low for greater than 1ms, the transmitter is disabled, driving the bus to a recessive state to prevent bus locking.

What is the purpose of the VCC2 pin on the MAX13054?

The VCC2 pin serves as a dedicated logic supply input, allowing the transceiver to interface directly with +3.3V microcontrollers while the main VCC supply operates at +5V.

Does the MAX13054 support slope-control mode?

No, slope-control mode is a feature exclusive to the MAX13052 within this product family. The MAX13054 operates in standard high-speed mode only.
