ATA6629-TAPY

Drivers, Receivers, Transceivers Overview

The ATA6629-TAPY is a fully integrated LIN transceiver with an integrated low-drop voltage regulator, designed for automotive slave nodes. It supports supply voltages up to 40V and operates within a VS range of 5V to 27V. The device provides a regulated VCC output of 3.3V ±2% with an 85mA current capability. It complies with LIN specifications 2.0, 2.1, and SAEJ2602-2, supporting data rates up to 20kBaud. Key electrical parameters include a typical sleep mode supply current of 10µA and silent mode current of 35µA. The NRES pin provides undervoltage reset functionality with a 4ms delay.

Drivers, Receivers, Transceivers Procurement Notes

Verify the component manufacturer origin, as Atmel was acquired by Microchip Technology. Confirm that the specific ordering suffix matches the required tape and reel packaging format. Ensure the datasheet revision aligns with your design requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the ATA6629 specifically when a 3.3V regulated output is required for the connected microcontroller. Choose this part over the ATA6631 if the system logic operates at 3.3V rather than 5V. Consider the thermal resistance characteristics and PCB heat sink requirements for high load currents.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ATA6629/ATA6631 family of LIN System Basis Chips originally developed by Atmel Corporation. Following the acquisition of Atmel by Microchip Technology, these products are now managed under the Microchip portfolio. The series is designed to simplify the implementation of LIN bus interfaces in automotive applications.
