The UCC3626DW is a power management integrated circuit (PMIC) which primarily functions as a motor controller. It is a platform of drivers and controllers that helps to efficiently and safely drive motors, power regulators, and power converters. It is designed to provide complete, reliable and cost-effective power management solutions for various motor control applications. The UCC3626DW is designed to work with any motor application from basic PWM motor driving to advanced Field Oriented Control (FOC) motor control.

The UCC3626DW is an integrated platform of controllers, drivers and protection. It comprises of Half H-Bridge (HHB) drivers, current-mode, PWM sinusoidal controllers, FOC controllers, and gate drivers. The HHB drivers feature independent RDSon with temperature compensation, adjustable OCP for self-protection and low voltage operation with tight tolerances which helps in improving efficiency. It has an integrated fifth-order sigma-delta modulator which provides dead-time and current-mode control by minimizing digital noise and PWM ripple. The FOC controller enables precise control of rotor\'s speed, position and torque enabling precise synchronization of multiple motors. Four digital isolators are included in the UCC3626DW which improves electromagnetic compatibility while protecting the device from EMI. An advanced protection suite including UVLO, Cycle-by-Cycle OCP and OVP is also included.

Applications for the UCC3626DW includes systems requiring precise FOC motor control such as HVAC systems, appliances and automation systems. The integrated protection scheme ensures safe and reliable operation in any environment. The motor control module can be used in various motor types such as BLDC, ACIM, PMSM and SRM motors. It is designed to meet the requirements of various motor drives from low-voltage, low-power applications like small fans and pumps to high-voltage, high-current applications like doors and sunshades of cars and trucks.

The UCC3626DW provides a cost-effective and time-saving solution for motor control applications. Its integrated current-mode and FOC controllers provide precise and efficient control over motors. The integrated protection scheme provides comprehensive protection for the motor with quick detecting and fault signals, eliminating the need for additional components or circuits. It is designed to facilitate the development of a wide range of motor control applications from consumer electronics to industrial applications.
