ATA6832N-PIQW

Overview

The ATA6832N-PIQW is a fully integrated motor driver featuring three half-bridge outputs, manufactured by Microchip Technology. It utilizes Power MOSFET technology and supports PWM and SPI interfaces for control. The device operates with a supply voltage range of 4.75V to 5.25V and handles load voltages from 5.5V to 40V. Designed for high-temperature environments, it functions within a junction temperature range of -40°C to 200°C. The component is housed in an 18-VQFN (4x4) surface-mount package.

Feature Summary

• Integrates three half-bridge drivers with control and power stages
• Supports PWM and SPI communication interfaces
• Rated for high junction temperatures up to 200°C

Applications

• Automotive motor control systems
• High-temperature industrial actuation
• Power management integration

Procurement Notes

Verify the specific suffix 'N' indicates the extended temperature rating and package variant. Confirm interface compatibility with host controllers supporting SPI or PWM signals. Ensure thermal management solutions accommodate the 200°C junction temperature specification during operation.

Selection Notes

Select this component when designing systems requiring multiple half-bridge outputs in a compact form factor. Consider the 40V load voltage limit and 5V logic supply requirements. Evaluate the need for high-temperature resilience exceeding standard automotive grades.

Part Context

This part belongs to the ATA68xx series of gate drivers from Microchip Technology. It is related to variants such as the ATA6832C and ATA6831N, which offer similar half-bridge configurations but may differ in channel count or specific qualification standards.

Replacement Considerations

Check datasheets for the ATA6832C-PIQW-1 for potential design-in alternatives. Verify pinout compatibility and electrical parameter overlaps before substituting.
