BD6961F

Datasheet DC Brushless Fan Motor Driver Standard Single-phase Full wave Fan motor driver BD6961F Description This is the summary of application for BD6961F. BD6961F can drive FAN motor silently by BTL soft switching, and it can control rotational speed by PWM signal. Features ■ BTL soft switching drive ■ PWM speed control ■ Quick start function ■ Lock protection and auto restart (without external capacitor) ■ Rotating speed pulse signal (FG) output Package SOP8 W(Typ) x D(Typ) x H(Max) 5.00mm x 6.20mm x 1.71mm Application PC, PC peripheral component (Power supply, VGA card, case FAN etc.) BD player, Projector etc. Absolute Maximum Ratings Parameter Symbol Limit Supply Voltage Power Dissipation VCC Pd 15 0.78(Note 1) Operating Temperature Topr -40 to +105 Storage Temperature Tstg -55 to +150 Output Voltage VOMAX 15 Output Current IOMAX 1000(Note 2) FG Signal Output Voltage VFG 15 FG Signal Output Current IFG 10 Junction Temperature Tjmax 150 (Note 1) Reduce by 6.24mW/°C over 25°C. (On 70.0mm×70.0mm×1.6mm glass epoxy board) (Note 2) This value is not to exceed Pd. SOP8 Unit V W °C °C V mA V mA °C Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. ○Produ...
