ATA6626C-PGPW

Drivers, Receivers, Transceivers Overview

The ATA6626C-PGPW is a LIN System Basis Chip (SBC) manufactured by Microchip Technology, housed in a 20-lead QFN package measuring 5mm x 5mm. It integrates a LIN transceiver compliant with LIN 2.0, 2.1, and SAEJ2602-2 standards, featuring a 5V linear low-drop voltage regulator with an 85mA current capability. The device supports supply voltages from 5V to 27V, with typical sleep mode current of 10µA and silent mode current of 57µA. Unlike the ATA6624, the ATA6626 disables the TXD time-out timer, allowing unlimited dominant level switching via TXD for low data rates.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a LIN physical layer transceiver compliant with LIN 2.0, 2.1, and SAEJ2602-2 specifications.
• Includes a 5V linear low-drop voltage regulator capable of sourcing up to 85mA with undervoltage detection.
• Features an adjustable window watchdog with external timing resistor support and negative trigger input.
• Supports multiple wake-up sources including LIN bus, WAKE pin, KL_15 ignition detection, and EN pin.

Drivers, Receivers, Transceivers Applications

• Low-speed data communication nodes in automotive convenience electronics.
• Master and slave node implementations for LIN-bus systems.
• Vehicle interface circuits requiring robust EMC and ESD protection.

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific C suffix variant matches design requirements regarding the disabled TXD time-out timer. Ensure compliance with RoHS3 directives and check for any relevant Product Change Notices affecting marking or packaging before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select the ATA6626C-PGPW when a 5V regulator output is required alongside LIN transceiver functionality. Choose this model over the ATA6624 specifically if the application requires disabling the TXD time-out timer to allow continuous dominant bus states at low data rates. Ensure the system operates within the 5V to 27V supply range and utilizes the 20-pin QFN footprint.

Drivers, Receivers, Transceivers Part Context

The ATA6626C-PGPW belongs to the Atmel/Microchip ATA662x family of LIN System Basis Chips. It shares core architecture with the ATA6622 and ATA6624 but differs in regulator voltage and timer configuration. The 'C' suffix typically denotes automotive-grade qualification, while 'PGPW' indicates the specific QFN package type and lead finish.

Drivers, Receivers, Transceivers Replacement Considerations

The ATA6624C-PGPW is a functional substitute if the TXD time-out timer is required. The ATA6622C-PGPW serves as a replacement if a 3.3V regulator output is needed instead of 5V. Verify that the alternative part number's specific feature set aligns with the original design constraints.
