Description
The MP6630 is a 3-phase, brushless DC motor driver with integrated power MOSFETs for notebook fan drivers. The input voltage ranges from 2V to 5.5V.
The device controls the motor speed through a PWM signal on the PWM pin. It features an embedded single Hall sensor for robust start-up performance, sine-wave control for high efficiency and low-speed ripple / vibration over the full speed range.
The MP6630 also has a rotational speed detector. The FG pin is an open-drain output that detects rotational speed.
Protection features include under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6630 is available in a UTQNF-8 (2mmx3mm) package.
Advantages Include:
- Sine-wave & single Hall for high efficiency and robust start-up
- Flexible programmable starting duty
- Fewer external components
- Low RDS(ON), UTQFN (2mmx3mm) package
