The DRV11873PWPR is an Integrated Circuit (IC) component developed by Texas Instruments. It is a three-phase brushless DC (BLDC) motor controller specifically designed for low-power motor applications. The DRV11873PWPR offers various key features that make it suitable for a wide range of motor control applications.
One of the significant features of the DRV11873PWPR is its ability to drive up to 3A of continuous current per phase. This capability makes it suitable for driving small to medium-sized BLDC motors with high efficiency. The IC's small package size, measuring only 20-pin HTSSOP, allows for space-saving on printed circuit boards.
The DRV11873PWPR also features a simple control interface. It supports both analog and PWM (pulse width modulation) control inputs, providing flexibility for motor speed and torque control. The built-in feedback mechanism ensures accurate and reliable motor operation, eliminating the need for external feedback components.
To ensure robust protection, the DRV11873PWPR incorporates various safety features. It includes thermal shutdown protection, preventing the IC from operating under excessive temperature conditions. The integrated overcurrent protection safeguards the motor and the IC by shutting down the system when the current exceeds a predefined threshold.
Furthermore, the DRV11873PWPR offers advanced fault detection mechanisms. These include open-winding detection and locked rotor detection, which help to identify motor faults and prevent potential damage
