MCF8315A FET BLDC Driver Texas Instruments MCF8315A FET BLDC Driver is a single-chip, code-free, and sensorless Field Oriented Control (FOC) control three-phase BLDC motor driver with code-free FOC. This Brushless-DC (BLDC) motor driver is designed for driving speed-controlled 12V to 24V BLDC or Permanent Magnet Synchronous Motor (PMSM) requiring up to 4A peak current. The MCF8315A driver integrates three ½-bridges with 40V absolute maximum capability and a low RDS(ON) of 240mΩ. This driver features built-in power management circuits, including a voltage-adjustable buck regulator and LDO that can be used to power external circuits.
