ATA6628-PGPW

Drivers, Receivers, Transceivers Overview

The ATA6628-PGPW is a fully integrated LIN System Basis Chip (SBC) compliant with LIN 2.0, 2.1, and SAEJ2602-2 specifications. It features a low-drop voltage regulator providing a stable 3.3V output at up to 85mA, alongside an adjustable window watchdog timer. The device supports master and slave operation with supply voltages ranging from 5V to 27V. Key operational modes include Normal, Silent, Sleep, and Fail-safe, ensuring minimized current consumption during standby. It includes high-speed mode for transmission rates up to 200kBaud and integrates battery voltage sensing via an internal 1:6 divider.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 3.3V/85mA linear low-drop voltage regulator with undervoltage detection
• Adjustable window watchdog timer with external resistor control
• Multiple wake-up sources including LIN bus, WAKE pin, and KL_15 ignition signal
• Advanced protection against short circuits, overtemperature, and reverse currents

Drivers, Receivers, Transceivers Applications

• Master and slave nodes in automotive LIN bus systems
• Vehicle convenience electronics requiring low-power standby modes
• Electronic control units needing integrated power management and communication
• Battery voltage monitoring applications using the internal voltage divider

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PGPW corresponds to the QFN-20 package and AEC-Q100 qualification status as documented in the official Microchip datasheet. Confirm that the ordering information matches the active part status and moisture sensitivity level requirements for your assembly process. Always reference the latest revision of the datasheet for any potential product change notifications or end-of-life updates.

Drivers, Receivers, Transceivers Selection Notes

Select the ATA6628 when a 3.3V regulator output is required; choose the ATA6630 if a 5V regulator is needed instead. Ensure the application utilizes the QFN-20 package footprint compatible with the 5mm x 5mm dimensions. Consider the need for high-speed mode up to 200kBaud for diagnostic purposes versus standard LIN speeds. Verify that the external components for the watchdog oscillator and voltage regulator compensation meet the specified capacitance and resistance ranges.

Drivers, Receivers, Transceivers Part Context

The ATA6628 belongs to the Atmel/Microchip LIN System Basis Chip family, designed specifically for automotive networking. It combines a LIN transceiver with power management functions to reduce component count in electronic control units. The device is qualified according to AEC-Q100 standards, ensuring reliability in harsh automotive environments. It serves as a cost-effective solution for developing simple yet powerful slave and master nodes for LIN-bus systems.

Drivers, Receivers, Transceivers Replacement Considerations

The ATA6630 is functionally identical but provides a 5V regulator output instead of 3.3V. No other direct substitutes are confirmed in the provided documentation. Verify compatibility with existing PCB layouts and software drivers when considering alternative parts.
