TIDA-00114, 5V, 3-Phase, Sensorless, Sinusoidal Motor System Reference Design with Variable Speed Control

TIDA-00114, BLDC Motor System Reference Design 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
