3-Phase Fan Driver with Integrated Hall Sensor

MP6630H and MP6630 are 3-phase brushless DC Fan drivers with integrated power MOSFETs and single Hall-effect sensor. MP6630H is 2V to 16V and MP6630 is 2V to 5.5V operating Input Voltage range, both of them can support max. 1.4A output current. They have embedded Hall-effect sensor and sine-wave control, embedded Hall-effect sensor promote robust start-up performance, sine-wave control enable high efficiency and low audible noise. Moreover, both of them have robust protection function: UVLO, locked-rotor protection, OCP, thermal shutdown protection and auto-recovery. They are available in UTQFN-8 (2mmx3mm) package, designed to driver 3-phase BLDC motors like Notebook Fans, Gaming Fans, etc
