The MP6630H is a 3-phase brushless DC motor driver with integrated power MOSFETs and single Hall-effect sensor. The input voltage ranges from 2V to 16V.
The device controls the motor speed through the PWM signal on the PWM pin. It features a single, embedded Hall-effect sensor for robust start-up performance. It also features sine-wave control methods for high efficiency, and low-speed ripple and vibration over the full speed range.
The MP6630H also has a rotational speed detector. The rotational speed detector (the FG/RD pin) is the output of an open drain. This pin is also selectable for lock indication output.
Rich protections are implemented in the MP6630H, such as under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6630H is available in a UTQFN-8 (2mmx3mm) package.
