Abstract :
A linear driver for small brushless DC motors has been developed that has the capability of maximizing the voltage delivered to the motor while providing commutation logic and full control. by using discrete p-n-p high-side transistor switches in conjunction with integrated saturable n-p-n low-side drivers, a total loss of under 1 V can be achieved at currents up to 2 A and complete motor control can be obtained from a 5 V power source
