MikroElektronika Brushless 21 Click 3 Phase Motor Drive for AMT49400 for Brushless DC Motor

The MikroElektronika Brushless 21 Click is a compact add on board suitable for controlling brushless DC motors with any MCU. This board features the AMT49400, an advanced 3 phase, sensor less BLDC motor driver with integrated power MOSFETs from Allegro Microsystems. The AMT49400 is rated for an operating voltage range from 4V to 16V. Motor rotation speed is controlled by applying a duty cycle command to the PWM input, while a simple I2C interface is provided for setting motor rated voltage, rated current, rated speed, resistance, and start up profiles. Besides it also features additional diagnostic circuits and drive control functions such as motor lock detection and over current protection. This Click board makes the perfect solution for home appliances such as pumps and cooling fans, industrial equipment, and more.
