MP6630 - 3-Phase Fan Driver

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.

Features

  • an embedded single Hall sensor for robust start-up performance and 180° full-wave sine-wave control, which provides high efficiency, a low speed ripple, and low vibration across 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, overcurrent protection (OCP), and thermal shutdown protection. The MP6630 is available in a UTQNF-8 (2.
