AMT49413K - Automotive 3-Phase BLDC Controller and MOSFET Driver

Datasheet Summary

Description

The AMT49413K is a 3-phase brushless DC (BLDC) motor controller for use with N-channel external power MOSFETs.

It incorporates much of the circuitry required to design a cost-effective three-phase motor drive system, and has been specifically designed for automotive applications.

Features

  • High current 3-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.
