MAX13050ASA-T

Drivers, Receivers, Transceivers Overview

The MAX13050ASA-T is a high-speed CAN transceiver in an 8-pin SO package, rated for -40°C to +125°C. It supports data rates up to 1Mbps with ±80V fault protection on CANH/CANL and ±8kV ESD protection. Operating from a 4.75V to 5.25V supply, it draws 12.5mA typically. Features include a SPLIT pin for common-mode stabilization, standby mode, dominant timeout, thermal shutdown, and short-circuit protection.

Drivers, Receivers, Transceivers Feature Summary

• Extended ±80V fault protection on bus lines for harsh industrial environments
• SPLIT pin provides DC common-mode stabilization voltage
• Transmitter dominant timeout prevents bus clamping during controller faults
• Low-current standby mode with wake-up detection capability

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging rather than tube. Confirm the 'A' designation ensures operation across the full -40°C to +125°C automotive temperature range. Ensure the component is lead-free and RoHS compliant as indicated by the '+' suffix in official documentation.

Drivers, Receivers, Transceivers Selection Notes

Select this part when ±80V fault protection and common-mode stabilization are required. The MAX13050 lacks slope control found in the MAX13052 and silent mode of the MAX13053. It is suitable for standard 5V logic interfaces without the separate VCC2 supply needed for the MAX13054.

Drivers, Receivers, Transceivers Part Context

Part of the MAX13050/MAX13052/MAX13053/MAX13054 family sharing pin compatibility. The MAX13050 specifically includes the SPLIT pin but excludes the slope-control resistor input (RS) and silent mode (S) features present in other variants.

Drivers, Receivers, Transceivers Replacement Considerations

Public datasheet lists TJA1040 as a pin-for-pin replacement for the MAX13050 series.

Drivers, Receivers, Transceivers FAQ

How does the SPLIT pin function?

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

What is the dominant timeout duration?

If the TXD input remains low for greater than 1ms, the transmitter disables and drives the bus to a recessive state to prevent bus locking.

Does the MAX13050 support slope control?

No, the MAX13050 does not have an RS pin. Slope control is available only in the MAX13052 variant.
