ATA6623C-TAQY

Drivers, Receivers, Transceivers Overview

The ATA6623C-TAQY is a LIN transceiver with an integrated voltage regulator, designed for automotive slave nodes. It operates within a supply voltage range of 5V to 27V and supports up to 40V. The device provides a 3.3V output at 85mA. Electrical characteristics include a typical sleep mode current of 10µA and silent mode current of 57µA. It complies with LIN 2.0, 2.1, and SAEJ2602-2 standards. The component features undervoltage detection, short-circuit protection, and thermal shutdown. It is housed in an SO8 package.

• Supports normal, fail-safe, and silent modes for optimized power management
• Includes wake-up capability via the LIN bus line
• Features advanced EMC and ESD performance with interference protection

Drivers, Receivers, Transceivers Applications

• Automotive convenience electronics systems
• LIN Bus slave node development
• Low-speed data communication in vehicles

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix TAQY against official Microchip documentation to confirm tape and reel packaging details. Confirm RoHS compliance status through the manufacturer's latest product change notifications or datasheet revision history before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3V regulated output is required alongside LIN physical layer connectivity. Ensure the application load does not exceed the 85mA regulator limit. Verify that the system operates within the specified -40°C to +150°C junction temperature range and utilizes the SO8 package footprint.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ATA6623C/ATA6625C family of LIN System Basis Chips manufactured by Microchip Technology (formerly Atmel). The ATA6623C variant specifically provides a 3.3V regulator, whereas the ATA6625C provides a 5.0V regulator. Both share identical pinouts and functional capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

The ATA6625C-TAQY serves as a direct functional substitute if a 5.0V regulator output is acceptable instead of 3.3V. Other variants within the ATA6623C series may be considered based on specific packaging or environmental requirements.
