Datasheet DC Brushless Fan Motor Driver Standard Single-phase Full wave Fan motor driver BD6962FVM Description This is the summary of application for BD6962FVM. BD6962FVM can drive FAN motor silently by BTL soft switching, and it can control rotational speed by PWM signal. Features Package W(Typ) x D(Typ) x H(Max) MSOP8 2.90mm x 4.00mm x 0.90mm Compact package (MSOP8) BTL soft switching drive PWM speed control Quick start function Lock protection and auto restart (without external capacitor) Rotating speed pulse signal (FG) output Application PC, PC peripheral component (Power supply, VGA card, case FAN etc.) BD player, Projector etc. MSOP8 Absolute Maximum Ratings Unit Parameter Symbol Limit Supply Voltage 15 VCC V (Note 1) Power Dissipation Pd 0.58 W Operating Temperature Topr -40 to +105 C Storage Temperature -55 to +150 Tstg C Output Voltage 15 VOMAX V (Note 2) Output Current 800 IOMAX mA FG Signal Output Voltage V 15 V FG FG Signal Output Current 10 I mA FG Junction Temperature 150 Tjmax C (Note 1) Reduce by 4.68mW/C over 25C. (On 70.0mm70.0mm1.6mm glass epoxy board) (Note 2) This value is not to exceed Pd. 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.
