Texas Instruments High-Performance Analog Motor Drivers, Controllers UCC3626DWTR

The UCC3626DWTR is a motor controller designed for high-performance applications involving two- or four-quadrant, three-phase brushless DC motors. It integrates essential functions such as rotor position decoding, providing six outputs to control an external power stage. The device supports both voltage- and current-mode PWM motor control through a precision triangle oscillator and latched comparator. Key features include an integrated absolute value current amplifier for accurate motor current reconstruction, pulse-by-pulse and average current sensing for overcurrent protection, and a variable duty-cycle tachometer output for closed-loop speed control. The device also offers commands for coast, brake, and direction control, along with a direction output. The UCC3626DWTR operates within a supply voltage range of 11V to 14.5V and is available in a 28-pin SOIC package, making it suitable for various motor control applications.
