The Texas Instruments DRV10866DSCR is a fully integrated BLDC motor driver combining the control logic and three half-bridge power stages in a single 10-WSON (3x3 mm) package. It is designed specifically for small brushless-DC fan motors and similar low-voltage, low-power rotating loads where board area is tight. The PWM interface accepts a simple speed-control signal; the internal power MOSFETs handle the commutation. Supply and load voltage share the same 1.65 V to 5.5 V rail, so a single battery or regulated bus powers both the logic and the motor windings.
Each of the three half-bridges is rated for 800 mA continuous output. That limits the driver to small BLDC fans, pumps, and blowers.
