This BLDC motor system implements a DRV10963, a TLC555 timer, and a generic 5V motor. The sinusoidal control scheme is suitable for small fan applications where low noise is desired. Motor voltage support is 2.1V to 5.5V, and max current is 500mA. Motor speed is controlled by the PWM input. Low quiescent current standby mode is available. The motor drive stage has integrated protection, including short-circuit, shoot-through, under-voltage, over-temperature, and locked rotor detection.
