MCF8361A Sensorless FOC 3-Phase BLDC Driver Texas Instruments MCF8361A Sensorless Field Oriented Control (FOC) 3-Phase Brushless DC Motor (BLDC) Driver provides a single-chip, code-free, sensorless FOC solution for driving speed-controlled 12V to 24V BLDC or Permanent Magnet Synchronous Motors (PMSM) with 8A peak current capability. The MCF8316A integrates three 1/2H bridges with 40V absolute maximum capability and a very low RDS(ON) of 95mΩ (high-side plus low-side). Power management features of an adjustable buck regulator and LDO generate the 3.3V or 5.0V voltage rails and can be used to power external circuits.
