MAX13052ASA+T

Drivers, Receivers, Transceivers Overview

The MAX13052ASA+T is a high-speed CAN transceiver from the MAX1305x family, manufactured by Analog Devices Inc./Maxim Integrated. 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 CANH and CANL pins, exceeding ISO11898 specifications with an input common-mode range greater than ±12V. It includes slope-control mode for slew-rate programming via an external resistor connected to the RS pin, allowing operation at reduced speeds up to 500kbps to minimize EMI. The component provides a SPLIT pin for common-mode stabilization and offers ±8kV IEC 61000-4-2 ESD protection. It is housed in an 8-pin SO package and specified for temperatures from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Slope-control mode enables programmable transmitter slew rate via an external resistor to reduce electromagnetic interference.
• Extended ±80V fault protection on bus lines ensures robustness in harsh industrial environments.
• Common-mode stabilization output (SPLIT) maintains recessive voltage levels under leakage conditions.

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes requiring high-speed communication
• Medium- and heavy-duty truck systems
• Industrial network applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the '+A' designation corresponds to the extended temperature range of -40°C to +125°C. Ensure compatibility with the 8-pin SO package outline during PCB layout planning. Cross-reference the manufacturer's latest documentation for any updates to the RoHS compliance status or material declarations prior to final procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when both high-speed operation up to 1Mbps and slope-control capabilities are required for EMI reduction. It is suitable for designs needing common-mode stabilization via the SPLIT pin. Consider alternatives if silent mode or separate 3.3V logic supplies are necessary, as these features belong to other members of the MAX1305x family.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13050/MAX13052/MAX13053/MAX13054 series of industry-standard high-speed CAN transceivers. These devices are pin-for-pin compatible, sharing the same functional block diagram structure while differing in specific control pins like STBY, RS, REF, and VCC2. The MAX13052 specifically adds the RS pin for slope control compared to the standard MAX13050.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include PCA82C250/51. Verify pinout compatibility and electrical characteristics before substitution.

Drivers, Receivers, Transceivers FAQ

How is the slope-control mode activated on the MAX13052?

Connect a resistor between the RS pin and ground. The resistance value determines the slew rate, allowing operation at data rates up to 500kbps.

What is the function of the SPLIT pin?

The SPLIT pin provides a DC common-mode stabilization voltage equal to 0.5 x VCC, stabilizing the recessive voltage against leakage currents from unsupplied transceivers.

Does the MAX13052 support silent mode?

No, silent mode is a feature exclusive to the MAX13053 within this family. The MAX13052 utilizes standby mode controlled by the RS pin.
