The NCT3945S TR provides enhanced features, reliability and robustness for design and operation in conjunction with power supply and battery management systems. It is a 3-Phase Brushless DC (BLDC) Motor Controller and Driver which operates at over- and under-voltage to optimize performance. It is optimized to work with high-power BLDC motors, with up to 4 Amps of current and up to 16 different pulse widths to control the motor.

The NCT3945S TR features features a powerful and easy to use control interface, designed to meet the most demanding applications, including motor speed and position control, vibration control, and power supply diagnostics. A pulse-width modulation engine can be implemented to dynamically adjust the voltage and current to match the motor speed, enabling the BLDC motors to reach their highest performance range, as well as a frequency counter and analog/digital inputs and outputs for synchronization to external clocks, such as the PCIe bus.

The NCT3945S TR is easy to integrate into existing motor control systems, since it contains its own self-contained library of motor control algorithms, avoiding the need for complicated integration with external motor control software. It also offers two modes of operation: Active PWM, which is suitable for high-power applications, and Digital PWM, which reduces noise and power consumption when lower power applications are in use.

The NCT3945S TR features an integrated fault protection system, designed to protect the motor, system and user from potential damage due to over or under-voltage, over current or over temperature situations. It also provides protection against unexpected voltage switching and electro-PV spikes.

Moreover, the NCT3945S TR has an optional brake feature, which can be used to stop the motor in the event of an error or over-voltage situation. This feature can be controlled according to the motor speed and commanded motor direction, and helps ensure fast, safe and efficient stopping of the motor.

Overall, the NCT3945S TR is an advanced motor controller and driver, designed to optimize system performance and reduce user cost by minimizing component count and power consumption. It is fully compatible with existing motor control systems, and makes it easy to create efficient and reliable motor controllers with a smaller footprint and lower component costs than traditional designs.
