Le Brushless 2 Click Board™ est équipé du contrôleur de moteur BLDC DRV10964 avec un étage de sortie intégré. Le Click Board™ est conçu pour fonctionner sur une alimentation 3,3 V ou 5 V.
Il communique avec le microcontrôleur cible via les broches suivantes sur MikroBUS : AN, RST, CS, PWM, INT.
The Brushless 2 Click Board™ 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 Does The Brushless 2 Click Board™ Work?
A 3 wire BLDC motor can be connected over the screw terminals; speed is controlled through PWM pin on the mikroBUS™ line. The Brushless 2 Click Board™ 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.
