MAX3058ASA

Overview

The MAX3058ASA is a high-speed CAN transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for robust communication in automotive and industrial environments. It supports data rates up to 1 Mb/s and operates within a supply voltage range of 4.5 V to 5.5 V. The device features low supply current consumption of 40 mA during operation and provides ESD protection rated at 12 kV. It functions reliably across an extended temperature range from -40°C to +125°C, with a maximum power dissipation of 470 mW. Packaged in an SOIC-8 surface-mount format, it integrates one driver and one receiver for half-duplex CAN protocol support.

Feature Summary

• High-speed data transmission capability supporting up to 1 Mb/s for efficient network communication
• Robust fault protection and electrostatic discharge resilience ensuring reliable operation in harsh electrical environments
• Low power consumption design suitable for battery-operated or energy-sensitive applications
• Extended thermal stability allowing consistent performance across wide industrial and automotive temperature ranges

Applications

• Automotive body control modules and engine management systems requiring CAN bus connectivity
• Industrial automation controllers and sensors utilizing CAN protocol for data exchange
• Medical equipment interfaces needing reliable serial communication with high noise immunity

Procurement Notes

Verify the specific suffix 'A' indicates the commercial temperature grade variant when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering quantities align with standard reel or cut-tape availability constraints defined by the distributor. Cross-reference the full part number including tape-and-reel indicators if automated assembly is required.

Selection Notes

Select this component when a 1 Mb/s data rate is sufficient for the application's bandwidth requirements. Choose this transceiver over higher-speed variants if lower electromagnetic interference and reduced power consumption are prioritized. Ensure the system voltage remains within the 4.5 V to 5.5 V window to maintain signal integrity. Verify that the SOIC-8 package dimensions fit the available PCB footprint constraints.

Part Context

This device belongs to the MAX305x family of CAN transceivers, which are engineered for high reliability in noisy environments. It shares architectural similarities with other Maxim Integrated interface ICs but is distinct in its specific speed and power profile. The series is widely recognized for its balance between performance and cost-effectiveness in standard CAN networks.

Replacement Considerations

Direct substitutes include the MAX3051ASA for 500 kb/s operation or the MAX3052ASA for 1 Mb/s with different pinout configurations. Verify compatibility with existing termination resistors and biasing networks when swapping between these variants.
