MCT8315A FET BLDC Driver Texas Instruments MCT8315A FET Brushless DC (BLDC) Driver is a single-chip, code-free, and sensorless trapezoidal control three-phase BLDC motor driver with 3kHz electrical frequency. This BLDC driver is designed for 12V to 24V BLDC motors requiring up to 4A peak current. The MCT8315A driver integrates three ½-bridges with 40V absolute maximum capability and a low RDS(ON) of 240mΩ (high-side + low-side FETs). This BLDC driver features built-in power management circuits, including a voltage-adjustable buck regulator and LDO that can be used to power external circuits.
