Brushless 4 click is a 3 phase sensorless BLDC motor driver, which features a 180° sinusoidal drive, providing high efficiency and low acoustic noise. This type of drivers inherently provides higher torque in general, compared to classical 120° BLDC motor drivers. Brushless 4 click allows a wide voltage range to be used for the power supply: from 2V, up to 14V. The Click board™ features a standard set of protection features: overvoltage protection, overtemperature protection, overcurrent limiting, but also some more specific protection features, such as the rotor lock-up protection and automatic restart function.
