ATA6566-GBQW1

Drivers, Receivers, Transceivers Overview

The ATA6566-GBQW1 is a high-speed CAN transceiver designed for automotive applications, compliant with ISO 11898-2 and SAE J2962-2 standards. It supports communication speeds up to 2 Mbit/s and features a dedicated standby mode with remote wake-up capability via the CAN bus. The device operates within a supply voltage range of 4.75 V to 5.25 V on the VCC pin and 2.8 V to 5.5 V on the VIO pin. It is qualified to AEC-Q100 Grade 1 standards, ensuring reliable operation across an ambient temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Compliant with Japanese OEM requirements and certified according to the latest VeLIO test specification.
• Features a low-power standby mode with remote wake-up capability triggered by specific patterns on the CAN bus.
• Includes fail-safe mechanisms such as TXD dominant time-out, undervoltage detection, and overtemperature protection.
• Provides direct interfacing to microcontrollers with supply voltages from 3V to 5V through the VIO pin.

Drivers, Receivers, Transceivers Applications

• Classical CAN networks in automotive systems
• CAN FD networks in industrial environments
• Aerospace and medical equipment interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GBQW1 to confirm the package type and temperature grade. Ensure that the procurement documentation matches the required AEC-Q100 Grade 1 qualification. Confirm compatibility with the target microcontroller's I/O voltage levels before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for high-speed CAN networks requiring low standby current and robust wake-up functionality. The GBQW1 variant is suitable for applications needing operation up to +125°C ambient temperature. Ensure the design accommodates the VIO pin for proper logic level translation with the host controller.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ATA6566 family of high-speed CAN transceivers. It shares functional similarities with other variants like the ATA6566-GAQW1 but differs in packaging and thermal characteristics. The family is optimized for automotive use, offering enhanced EMC performance and compliance with strict industry standards.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other members of the ATA6566 family, such as the ATA6566-GAQW1, provided the package and temperature grade requirements are met. Verify that any substitute maintains the same VDFN8 package and Grade 1 qualification.
