DESCRIPTION

The MP6650 is a single-phase, brushless, DC motor driver with integrated power MOSFETs and a Hall-effect sensor. 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 and input line reversevoltage protection (RVP) to save the external diode on the supply line.

The device 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. The output speed vs. the input duty curve can be configured easily for flexible use. To reduce audible fan driver noise and power loss, the MP6650 features a soft on/off phase transition and an automatic phaselock function of the motor winding BEMF and current.

Full protection features include input overvoltage protection (OVP), under-voltage 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. It is available in TSOT23-6-L, TSOT23-6-R, TSOT23-6-SL, and TSOT23-6-RSL packages.
