ATA6828-T2QY

Overview

The ATA6828-T2QY is a fully integrated brushed DC motor driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.75V to 5.25V and supports load voltages from 5.6V to 40V. The device utilizes BCDMOS technology and features an SPI interface for control. It provides a typical output current of 1.5A per channel with a peak output capability, housed in a 14-SOIC package. The component includes comprehensive fault protection mechanisms such as UVLO, over-temperature, short circuit, and open load detection.

Feature Summary

• Fully integrated gate driver with control and power stages for brushed DC motors
• SPI serial interface for configuration and status monitoring
• Integrated state flag and multiple fault protection features including UVLO and thermal shutdown

Applications

• Brushed DC motor control systems
• Automotive lighting applications
• Resistive load driving

Procurement Notes

Verify the obsolete part status before procurement planning. Confirm that the 14-SOIC package dimensions match the target PCB footprint. Ensure the 4.75V to 5.25V supply voltage requirement aligns with the system design. Check for available substitute components due to end-of-life status.

Selection Notes

Select this component for applications requiring a single-chip solution for brushed DC motor control with SPI communication. The low operating supply current of 6 mA makes it suitable for power-sensitive designs. Verify compatibility with the required load voltage range up to 40V and ensure adequate thermal management for the SOIC package.

Part Context

This part belongs to the Microchip Technology gate driver family, specifically designed for half-bridge configurations. It integrates the necessary logic and power stages to drive external loads efficiently. The device is distinct from general-purpose drivers by its specific focus on automotive and industrial motor control applications with built-in diagnostic capabilities.

Replacement Considerations

The related T6818 series shares similar specifications but may differ in pinout or specific electrical characteristics. Verify functional equivalence before substitution. No direct public substitute part numbers are confirmed for this obsolete model.
