MP6650GJS-0000-P

The MP6650 is a single-phase, brushless, DC motor driver with integrated power MOSFETs and a hall effect sensor in TSOT23-6-RSL package. The device drives single-phase brushless DC fan motors with up to 2A of output current. The IC has a 3.3V to 18V input voltage range. It controls the rotational speed through the PWM signal on the PWM pin. It has a rotational speed detection feature and rotor lock fault indication on the FG/RD pin with an open-drain output. To reduce audible fan driver noise and power loss, the MP6650 features a soft on/off phase transition and an automatic phase-lock function of the motor winding BEMF and current. Full protection features include input overvoltage protection (OVP), undervoltage lockout (UVLO), rotor deadlock (RD) protection, thermal shutdown and input reverse protection. The MP6650 requires a minimal number of external components to save solution cost. Typical application includes CPU fan for personal computers or servers and brushless DC motors.
