Overview
The ATA6832C-PIQW-1 is a high-temperature triple half-bridge driver manufactured by Microchip Technology. It integrates three high-side and three low-side drivers to control brushless DC (BLDC) motors. The device supports SPI and PWM interfaces for communication and control. It operates within a supply voltage range of 5.5V to 18V and is qualified to AEC-Q100 standards for automotive applications. The component is housed in a 48-VFQFN package with an exposed pad, designed for surface mount installation.
Feature Summary
- Integrates three half-bridge outputs formed by dedicated high-side and low-side drivers for BLDC motor control
- Supports serial peripheral interface (SPI) and pulse width modulation (PWM) for flexible system integration
- Designed for high-temperature operation suitable for demanding automotive environments
Applications
- Brushless DC (BLDC) motor drive systems
- Automotive electronic control units requiring high-temperature reliability
- Industrial motor control applications
Procurement Notes
Verify the specific suffix PIQW-1 against the official datasheet to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints for the 48-VFQFN package. Confirm that the SPI and PWM interface requirements align with the host controller capabilities before finalizing procurement.
Selection Notes
Select this component when a robust solution for driving three-phase BLDC motors is required in high-temperature environments. The integrated half-bridge structure reduces external component count compared to discrete solutions. Consider the AEC-Q100 qualification if the application mandates automotive-grade reliability standards.
