MAX3056ASD

Overview

The MAX3056ASD is a ±80V fault-protected CAN transceiver designed for 40kbps applications. It operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range from -40°C to +125°C. The device features built-in slope control to enable the use of unshielded cables while maintaining high noise immunity through receiver input filters. It provides full wake-up capability during failure modes and includes current-limiting and thermal-protection circuits to safeguard the transmitter output stage against overcurrent faults.

Feature Summary

• Supports single-wire transmission mode with ground offset voltages up to 1.5V
• Built-in slope-control feature allows the use of unshielded cables
• Guarantees full wake-up capability during failure modes
• Provides low-current sleep and standby modes with bus line wake-up

Applications

• Industrial HVAC systems
• Automotive networks requiring robust fault tolerance
• Industrial control networks

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Ensure compatibility with the target system's CAN controller logic levels. Confirm that the 14-SOIC footprint matches the PCB layout requirements. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component for applications requiring operation at 40kbps data rates. The integrated slope control is essential for reducing EMI when using unshielded cabling. Consider the ±80V fault protection for environments prone to electrical transients or wiring errors. Verify that the low-power modes meet the system's energy consumption constraints.

Part Context

This part belongs to the MAX3054/MAX3055/MAX3056 family of fault-protected CAN transceivers. While pin-compatible, it is distinct from the MAX3054 (250kbps) and MAX3055 (125kbps) due to its optimized data rate and specific slew-rate characteristics. It shares common fault management and low-power features with the series.

Replacement Considerations

The MAX3056ASD is functionally compatible with the TJA1054. When substituting, verify that the replacement device supports the same 40kbps data rate and ±80V fault protection specifications.
