MCF8315A - FET BLDC Driver

General Description

The MCF8315A provides a single-chip, code-free sensorless FOC solution for customers driving speedcontrolled 12- to 24-V brushless-DC motors (BLDC) or Permanent Magnet Synchronous motor (PMSM) up to 4-A peak current.

Key Features

  • Three-phase BLDC motor driver with integrated sensorless motor control algorithm.
  • Code-free Field Oriented Control (FOC).
  • Analog, PWM and freq. based speed input modes: available only when MCF8315A is configured as a standby device (DEV_MODE = 0b).
  • I2C based speed input mode: available in both sleep (DEV_MODE = 1b) and standby devices (DEV_MODE = 0b).
  • Offline motor parameters measurement with Motor Parameter Extraction Tool (MPET).
  • 5-point.
