Figure 5. The device can provide up to a 22 volt output from a -0.3 to 5.5 volt input. Logic 1 means 5V and Logic 0 means GND. A "motor drive" is not even necessary with brushed dc (BDC) motors in some applications. Generally, a BLDC motor drive uses one or more Hall sensors to keep the motor synchronized and running. If your motor has phases that are 1 each then it should measure 1 from center tap to each phase, but 2 between phases. . Certain BLDC motor drivers use the center tap to help measure BEMF for commutation! Stepdelay is the number of milli-seconds to wait before switching. Then test again my old BLDC motor code for sanity and redisgn a proper, small . The complete circuitry and output waveforms are available here. Alternatively, it can be used to drive one or two bi-directional DC motors (H-Bridge configuration, cascaded to support the second motor) or up to three uni-directional DC motors (half-bridge configuration).

The three-phase BLDC motor controller circuit includes six steps necessary to complete a full switching cycle (that is to energize all the three windings of the stator). In the circuit there are 2 pushbuttons, one is used to increase BLDC motor speed and the 2nd one is used to decrease it. While it's possible to vary the speed of a BDC motor using a simple voltage-divider approach, that's inefficient and is rarely used. In a nutshell, there're two types of BLDC motors. The two parts are inseparable, especially low-power circuits often integrate the two to form a single application specific integrated circuit. DRV10866 is specifically designed for low noise and low component-count fan-motor drive applications.
