ATA6662C-TAQY

Drivers, Receivers, Transceivers Overview

The ATA6662C-TAQY is a fully integrated LIN transceiver compliant with LIN specification 2.0, 2.1, and SAEJ2602-2. It operates within a supply voltage range of 5V to 27V and supports baud rates up to 20Kbaud. The device features improved slew rate control for secure data communication in automotive convenience electronics. It includes advanced EMI and ESD protection, withstanding over 6kV on the VS and LIN pins. The IC offers Normal and Sleep modes, with typical standby current of 10µA. Wake-up capabilities are provided via the LIN bus (90µs dominant) or an external WAKE pin (35µs low level).

Drivers, Receivers, Transceivers Procurement Notes

Verify the component manufacturer, as the datasheet originates from Atmel Corporation prior to its acquisition by Microchip Technology. Confirm that the specific ordering suffix TAQY corresponds to the SO8 package and taped and reeled format. Ensure the part meets the required automotive grade specifications if intended for vehicle applications.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for low-speed data communication systems requiring compatibility with both 3.3V and 5V logic devices. It is suitable for applications demanding minimal standby current and robust protection against ground shifts and battery disconnection. Consider the thermal characteristics and heat sink requirements for the SO8 package during design integration.

Drivers, Receivers, Transceivers Part Context

The ATA6662C is part of the Atmel LIN networking product line, designed specifically for the physical layer interface of Local Interconnect Network protocols. Following corporate acquisitions, Microchip Technology now manages this product family. The device serves as a bridge between the LIN protocol handler and the physical bus, ensuring reliable data transmission in harsh automotive environments.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Microchip resources for potential cross-references or updated components within the same functional category.

Drivers, Receivers, Transceivers FAQ

How does the ATA6662C handle ground disconnection?

The device does not affect the LIN Bus in the case of a GND disconnection and can handle a ground shift up to 11.5% of the supply voltage.

What is the function of the INH pin?

The INH pin controls an external switchable voltage regulator. It switches to the VS level during Normal Mode to activate the regulator and is left floating in Sleep Mode.

Can the device distinguish between wake-up sources?

Yes, the device distinguishes between local wake-up requests (pin WAKE) and remote wake-up requests (LIN bus), which can be read on the TXD pin in Fail-safe Mode.
