ATA6832-PIQW

Overview

The ATA6832-PIQW is a high-temperature triple half-bridge driver manufactured by Microchip Technology. It integrates three high-side and three low-side drivers to form three half-bridge outputs, designed for robust motor control applications. The device supports SPI communication and PWM input signals for precise control. It operates within an extended temperature range suitable for demanding automotive environments.

Feature Summary

• Integrates three half-bridge outputs formed by dedicated high-side and low-side drivers
• Supports serial peripheral interface (SPI) communication for configuration and monitoring
• Accepts pulse-width modulation (PWM) inputs for direct motor speed and direction control
• Engineered for high-temperature operation in harsh automotive conditions

Applications

• Automotive window lift motors
• Seat adjustment actuators
• Sunroof drive systems
• HVAC fan control units

Procurement Notes

Verify the specific suffix PIQW against the official Microchip datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels and SPI protocol requirements before integration. Check current availability status as automotive components may have limited stock or long lead times due to supply chain constraints.

Selection Notes

Select this component when a compact solution for driving three-phase or multiple single-phase DC motors is required. It is suitable for designs needing integrated power stages without external MOSFETs. Consider thermal management requirements given the high-temperature rating and integrated power dissipation capabilities of the half-bridge structure.

Part Context

This part belongs to the ATA68xx series of motor drivers from Microchip, formerly Atmel. These devices are widely used in automotive body electronics for controlling various electromechanical loads. The ATA6832 variant specifically focuses on triple half-bridge configurations, offering a cost-effective alternative to discrete driver solutions.

Replacement Considerations

ATA6832C is a similar variant within the same family. Verify pinout compatibility and electrical specifications before substitution. Other models like ATA6833C offer different interface options such as LIN bus instead of SPI.
