A3930 - Automotive 3-Phase BLDC Controller and MOSFET Driver

General Description

The A3930 and A3931 are three-phase brushless DC (BLDC) motor controllers for use with N-channel external power MOSFETs.

They incorporate much of the circuitry required to design a cost-effective three-phase motor drive system and have been specifically designed for automotive applications.

Key Features

  • High current three-phase gate drive for N-channel MOSFETs.
  • Synchronous rectification.
  • Cross-conduction protection.
  • Charge pump and top-off charge pump for 100% PWM.
  • Integrated commutation decoder logic.
  • Operation over 5.5 to 50 V supply voltage range.
  • Extensive diagnostics output.
  • Provides +5 V Hall sensor power.
  • Low-current sleep mode.
