ATA6843-PLQW-1

Overview

The ATA6843-PLQW-1 is a three-phase BLDC motor driver and controller manufactured by Microchip Technology. It integrates power MOSFETs and operates within a supply voltage range of 5.25 V to 32 V. The device supports LIN interface communication for network connectivity and includes features such as commutation control, direction management, and protection mechanisms. Packaged in a 48-VQFN (7x7 mm) with an exposed pad, it is designed for automotive applications requiring high reliability.

Feature Summary

Integrates three half-bridge pre-drivers with power MOSFETs for direct motor phase driving
Supports LIN bus communication for vehicle network integration and command reception
Provides comprehensive protection including over-current, over-temperature, and open-load detection

Applications

Automotive body electronics systems
Blind spot detection actuators
Power tailgate liftgate motors
Seat adjustment mechanisms

Procurement Notes

Verify the specific suffix -1 against official Microchip documentation to confirm package and temperature grade variations. Ensure compatibility with existing LIN transceivers and power supply rails before integration. Confirm end-of-life status or lifecycle recommendations through authorized distributors to mitigate long-term supply risks.

Selection Notes

Select this component when a single-chip solution for three-phase BLDC control is required in automotive environments. It is suitable for applications needing integrated power switching and LIN communication without external gate drivers. Consider thermal performance requirements due to the QFN package and ensure adequate PCB copper area for heat dissipation.

Part Context

This part belongs to the ATA68xx family of automotive-grade motor drivers from Microchip Technology. These devices are specifically engineered for low-voltage DC motor control in harsh automotive environments. The family shares common architectural features but varies in current ratings and specific protection configurations.
