MCF8315A Datasheet (Texas Instruments)

MCF8315A, FET BLDC Driver

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.

The MCF8315A integrates three ½-bridges with 40-V absolute maximum capability and a

MCF8315A Features
