BD61250MUV

Datasheet DC Brushless Fan Motor Driver Multifunction Single-phase Full-wave Fan Motor Driver BD61250MUV General Description BD61250MUV is pre-driver IC to drive single phase H bridge output composed of external MOS FET. The power supply input terminal and the drive output have voltage rating of 40V, so it can be used in a 24V power supply without using voltage drop down circuit. Features Pre driver for external power MOS FET Speed controllable by PWM / DC voltage Minimum output duty limit Input / output duty slope adjustment Silent drive by the PWM soft switching Lead angle setting Soft start Standby mode Current limit Lock protection and automatic restart Rotation speed pulse signal(FG), Lock alarm signal(AL) selectable Drive PWM frequency selectable (50kHz/25kHz) Application General consumer equipment of Desktop PC, Server, etc. Office equipment, Copier, FAX, Laser Printer, etc. Package VQFN024V4040 W (Typ) x D (Typ) x H (Max) 4.00mm x 4.00mm x 1.00mm VQFN024V4040 Absolute Maximum Ratings Parameter Symbol Rating Unit Supply Voltage Power Dissipation VCC 40 V Pd 0.83(Note 1) W Operating Temperature Range Topr -40 to +105 °C Storage Temperature Range Tstr -55 to +150 °C Maximum Junction Temperature Tjmax +150 °C High Side Output Voltage VOH VCC-7 to VCC V Low Side Output Voltage VOL 0 to 7 V Output Current IOMAX 10 mA Signal Output Voltage VSIG 40 V Signal Output Current ISIG 10 mA Reference Voltage (REF) Output Current IREF 10 mA Input...
