Brushless 3 Click Board™

Product Code: MIKROE-2766

The Brushless 3 Click Board™ carries the DRV10983, a three-phase sensorless motor driver with integrated power MOSFETs. When an external power supply is applied, you can drive a brushless DC motor through the PWM pin, AN pin or I2C interface. It communicates with the target microcontroller over I2C interface, with the additional functionality provided by the following pins on the mikroBUS™ line: PWM, AN, INT, RST. A 3 wire BLDC motor can be connected over the screw terminals. DRV10983 Driver Features The DRV10983 is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 2A. The DRV10983 uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which significantly reduces the pure tone acoustics that typically occurs as a result of commutation. The interface to the device is designed to be simple and flexible. The motor can be controlled directly through PWM, analog, or I2C inputs. Motor speed feedback is available through either the FG pin or I2C.

SPECIFICATIONS Type Brushless Applications The automotive industry, drones (because of the good power-to weight ratio of brushless motors), computers, medical equipment, HVAC systems, small home appliances, robotics, battery powered systems, small cooling fans in computers, toys, etc. On-board modules DRV10983, a three-phase sensorless motor driver with integrated power MOSFETs.
