MP6650

18V, 2A,Single-Phase, BLDC Motor Driver with Integrated Hall Sensor in a TSOT23-6 Package

Datasheet

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 reverse-voltage 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 phase-lock function of the motor winding BEMF and current.

Full protection features include input over-voltage 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.

Advantages Include:

Fewer external components with integrated power MOSFETs and Hall sensor
Low RDS(ON) (total 740mΩ HS + LS) and high efficiency
Digital programming speed curve
Extensive protection features and smaller package
