MCT8316Ax/MCT8316Ax-Q1 BLDC Motor Drivers

Texas Instruments MCT8316Ax/MCT8316Ax-Q1 High-Speed Sensorless Trapezoidal Control Brushless DC (BLDC) Motor Drivers provide single-chip, code-free, sensorless trapezoidal solutions for applications requiring high-speed operation (up to 3kHz electrical) or very fast startup times (< 50ms capable) for 12V to 24V BLDCs up to 8A peak current. The MCT8316Ax/MCT8316Ax-Q1 integrates three 1/2H bridges with 40V absolute maximum capability and a very low R_DS(ON) of 95mΩ (high-side plus low-side). Power management features of an adjustable buck regulator and LDO generate the device's 3.3V or 5.0V voltage rails and can power external circuits. The sensorless trapezoidal control is highly configurable through register settings (MCT8316AV/MCT8316AV-Q1) or hardware pins (MCT8316AT). Register settings for the MCT8316AV/MCT8316AV-Q1 component can be set in non-volatile EEPROM, allowing the device to operate stand-alone once configured. These devices receive a speed command through a PWM input, analog voltage, or I²C command.
