DESCRIPTION
The MP6517 is a single-phase, brushless, DC motor driver with integrated power MOSFETs and a Hall effect sensor. The MP6517 drives single-phase, brushless, DC fan motors with up to 1.2A of output current limit. The IC has a 3.3V to 18V input voltage range and input line reverse voltage protection to save the external diode on the supply line.
