Microchip ATA6847/ATA6847L 3-Phase Brushless Motor Gate Driver SBC

Integrated brushless motor control

The ATA6847 and ATA6847L deliver efficient 3-phase brushless motor control with built-in diagnostics, protection, and LIN communication. Supporting 3 V-42 V supply and full PWM duty-cycle, these SBCs enable reliable high-side/low-side switching. Multiple operational modes and ultra-low sleep currents optimize power usage in automotive and industrial applications.

Features

  • Supply range 3-42 V
  • Full PWM duty-cycle 0-100% with dual charge pumps
  • Integrated diagnostics and protection: over/under voltage, short-circuit, cross-conduction, current sense
  • Automotive grade: AEC-Q100 Grade 0, -40°C to +150°C
  • Multiple operational modes with ultra-low sleep currents (~20 µA)
  • LIN interface support (ATA6847L variant)

Applications

  • Automotive BLDC motor control: cooling fans, seat adjusters, sunroofs, steering, pumps
  • Home appliances with brushless motors
  • Robotics and drones, power tools, hobbyist electronics
  • Industrial motor systems requiring integrated diagnostics and protection
