Procurement Notes

Verify the specific suffix PLQW against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with 48-VQFN footprints during PCB layout. Cross-reference datasheet revisions to validate electrical characteristics and pin assignments before finalizing procurement orders.

Selection Notes

Select this component for applications requiring integrated gate driving and power switching in a compact form factor. Consider the 0.8μm SOI technology benefits for noise immunity and reliability. Evaluate the 5.25V to 32V input range against system power rails. Confirm that the 150°C junction temperature rating meets the thermal management requirements of the target enclosure.

Part Context

The ATA6843 belongs to a family of system basis chips developed by Microchip Technology (formerly Atmel). These devices are engineered specifically for complex motor control tasks, reducing bill-of-materials count by integrating multiple functions into a single silicon die. The series includes variants like the ATA6844 for extended temperature ranges.

Replacement Considerations

Public confirmed substitute part numbers include ATA6843-PLQW-1. Verify functional equivalence and pinout compatibility before substitution.
