MAX13053ASA+

Drivers, Receivers, Transceivers Overview

The MAX13053ASA+ is a high-speed CAN transceiver from Analog Devices/Maxim Integrated, designed for industrial networks requiring extended overvoltage protection. It supports data rates up to 1Mbps and features ±80V fault protection on the CANH and CANL bus lines. The device includes a silent mode that disables the transmitter while allowing RXD monitoring, and provides a reference output (REF) set to 0.5 x VCC for biasing older CAN controllers. It operates within a supply voltage range of 4.75V to 5.25V, with a typical recessive supply current of 12.5mA. The component offers ±8kV ESD protection per IEC 61000-4-2 and functions in temperatures from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Silent Mode operation allows disabling the transmitter while maintaining receiver functionality for bus monitoring.
• Integrated Reference Output (REF) provides a stable voltage for biasing differential comparators in legacy CAN controllers.
• Extended ±80V Fault Protection safeguards the device against severe overvoltage conditions on the bus lines.
• Dominant Timeout function prevents bus locking by automatically driving the bus recessive if TXD remains low for over 1ms.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates an automotive-grade temperature range (-40°C to +125°C) compared to the 'E' variant (-40°C to +85°C). Confirm package type is 8-pin SO. Ensure compatibility with existing board layouts due to pin-for-pin design within the family. Check for RoHS compliance status as indicated by the '+' suffix.

Drivers, Receivers, Transceivers Selection Notes

Select this part when silent mode operation is required alongside standard high-speed CAN communication. The integrated REF output simplifies interfacing with older microcontrollers lacking internal differential comparator biasing. Ensure the application environment requires ±80V fault protection rather than standard levels. Verify that the 5V logic interface matches the system's power supply constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13050/MAX13052/MAX13053/MAX13054 family of industry-standard high-speed CAN transceivers. All members share pin-for-pin compatibility and core features like ±80V fault protection. The MAX13053 specifically differentiates itself through the inclusion of Silent Mode and a dedicated Reference Output pin, distinguishing it from the MAX13050, MAX13052, and MAX13054 variants.

Drivers, Receivers, Transceivers Replacement Considerations

Public datasheet confirms TJA1050 and AMIS-30660 as pin-for-pin replacements for the MAX13053 series.
