ATA6831-PIQW

Overview

The ATA6831-PIQW is a high-voltage half-bridge gate driver manufactured by Microchip Technology. It integrates high-side and low-side drivers with internal power FETs, designed for robust motor control and power management applications. The device operates within an extended temperature range of -40°C to +150°C TJ and supports supply voltages up to 40V. Packaged in a compact 24-VQFN format, it facilitates surface-mount installation for space-constrained designs requiring reliable high-side and low-side switching capabilities.

Feature Summary

• Integrates both high-side and low-side gate drivers with built-in power FETs
• Supports operation in harsh environments with extended junction temperature ratings
• Designed for efficient power management and motor drive applications

Applications

• Brushed DC motor control systems
• General power management circuits
• Automotive electronic modules

Procurement Notes

Verify the specific suffix 'PIQW' against official Microchip documentation to confirm package type and tape-and-reel specifications. Confirm current production status as availability may vary. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when integrated high-side and low-side driving with internal FETs is required. Consider the 24-VQFN package for size constraints. Verify voltage headroom and thermal dissipation needs against the 40V limit and operating temperature range. Compare against standalone driver solutions if external FET flexibility is preferred.

Part Context

This part belongs to the ATA68xx series of high-voltage interface ICs from Microchip. These devices are engineered for automotive and industrial applications requiring reliable switching of inductive loads. The integration of drivers and FETs simplifies design complexity compared to discrete solutions.

Replacement Considerations

Check Microchip's official obsolescence notices for direct replacements. Evaluate cross-reference tools for comparable half-bridge drivers with similar pinouts and electrical characteristics if this specific suffix is unavailable.
