MCT8315Z - Sensored Trapezoidal Integrated FET BLDC Motor Driver

General Description

The MCT8315Z provides a single-chip, codefree sensored trapezoidal solution for customers driving 12-V/24-V brushless-DC motors; no external microcontroller is needed to spin the BLDC motor.

Key Features

  • Three-phase BLDC motor driver with integrated Sensored Trapezoidal control.
  • Hall sensor based trapezoidal (120°) commutation.
  • Supports analog or digital hall inputs.
  • Configurable PWM modulation: synchronous/ asynchronous.
  • Cycle-by-cycle current limit to limit phase current.
  • Supports up to 200-kHz PWM frequency.
  • Active demagnetization to reduce power losses.
  • 4.5-V to 35-V operating voltage (40-V abs max).
  • High outpu.
