1 / 17 page Datasheet ○Product structure:Silicon monolithic integrated circuit ○This product is not designed protection against radioactive rays 1/13 TSZ02201-0H1H0B100280-1-2 © 2012 ROHM Co., Ltd. All rights reserved. www.rohm.com 20.May.2014 Rev.002 TSZ22111・14・001 DC Brushless Fan Motor Driver Standard Single-phase Full wave Fan motor driver BD6964F Description This is the summary of application for BD6964F. BD6964F 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) ■ Lock alarm signal (AL) output Application PC, PC peripheral component (Power supply, VGA card, case FAN etc.) BD player, Projector etc. Package W(Typ) x D(Typ) x H(Max) SOP8 5.00mm x 6.20mm x 1.71mm Absolute Maximum Ratings Parameter Symbol Limit Unit Supply Voltage VCC 15 V Power Dissipation Pd 0.78(Note 1) W Operating Temperature Topr -40 to +105 °C Storage Temperature Tstg -55 to +150 °C Output Voltage VOMAX 15 V Output Current IOMAX 1000(Note 2) mA AL Signal Output Voltage VAL 15 V AL Signal Output Current IAL 10 mA Junction Temperature Tjmax 150 °C (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. 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. SOP8 |
