MIKROE-2754

        Brushless 2 click PID: MIKROE-2754         Brushless 2 click carries the DRV10964 BLDC motor controller with an integrated output stage from Texas Instruments. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over the following pins on the mikroBUS™ line: AN, RST, CS, PWM, INT. How the click works A 3 wire BLDC motor can be connected over the screw terminals; speed is controlled through PWM pin on the mikroBUS™ line. The click also has feedback on the interrupt pin (INT), so you can see exactly how fast the motor is going. DRV10964 motor driver features The DRV10964 is a three-phase sensorless motor driver with integrated power MOSFETs. It is specifically designed for high-efficiency, low-noise and low-external component count motor drive applications. The proprietary sensorless windowless 180° sinusoidal control scheme offers ultra-quiet motor drive performance. The DRV10964 contains an intelligent lock detect function, combined with other internal protection circuits to ensure safe operation.
