MAX13050ASA+T

Drivers, Receivers, Transceivers Overview

The MAX13050ASA+T is a high-speed CAN transceiver from Analog Devices/Maxim Integrated, designed for industrial networks requiring extended overvoltage protection. It operates within a supply voltage range of 4.75V to 5.25V and supports data rates up to 1Mbps. The device features ±80V fault protection on the CANH and CANL pins, exceeding standard specifications. It includes a dominant timeout function to prevent bus clamping if TXD remains low for more than 1ms. The SPLIT pin stabilizes recessive common-mode voltage. Operating temperatures range from -40°C to +125°C in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Extended ±80V fault protection on CANH and CANL pins for harsh environments
• Dominant timeout function prevents erroneous bus clamping during stuck TXD conditions
• SPLIT pin provides DC common-mode stabilization for improved network reliability
• Low-current standby mode with wake-up detection capability

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes
• Medium- and heavy-duty truck systems
• Industrial control networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates the -40°C to +125°C temperature grade and '+T' denotes tape-and-reel packaging. Confirm the manufacturer is Analog Devices Inc. or Maxim Integrated. Ensure the component matches the 8-pin SO package outline. Cross-reference the datasheet revision to ensure compatibility with current design requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this part when ±80V fault protection is required for CAN bus lines. It is suitable for applications needing dominant timeout protection and common-mode stabilization via the SPLIT pin. Compare against MAX13052 if slope-control is needed, or MAX13054 for 3.3V logic interfaces. Ensure the operating environment stays within the specified -40°C to +125°C range.

Drivers, Receivers, Transceivers Part Context

The MAX13050 is part of the MAX13050/MAX13052/MAX13053/MAX13054 family of industry-standard high-speed CAN transceivers. These devices are pin-for-pin compatible and share similar core functionalities while offering distinct features like slope-control (MAX13052), silent mode (MAX13053), or 3.3V logic support (MAX13054).

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include TJA1040 for the MAX13050 and PCA82C250/PCA82C51 for the MAX13052. Verify pinout compatibility and electrical characteristics before substitution.

Drivers, Receivers, Transceivers FAQ

What is the purpose of the SPLIT pin?

The SPLIT pin provides a DC common-mode stabilization voltage equal to 0.5 x VCC. It stabilizes the recessive voltage when unsupplied transceivers cause leakage currents.

How does the dominant timeout function work?

If the TXD input is held low for greater than 1ms, the transmitter disables and drives the bus to a recessive state, preventing erroneous controllers from clamping the bus.

What is the ESD protection rating?

The device offers ±8kV IEC 61000-4-2 Contact Discharge ESD protection per IBEE test facility standards.
