Datasheet DC Brushless Motor Drivers for Fans Standard Single-phase Full wave Fan Motor Driver BD69830FV Description The BD69830FV is a 24V single-coil brushless DC FAN motor driver. The device incorporates high efficiency DMOS H-bridge driver, regulated voltage output for hall element, and rotation speed is controlled by input PWM signal. Features Package W(Typ) x D(Typ) x H(Max) Power DMOS FET integrated SSOP-B14 5.00mm x 6.40mm x 1.35mm Direct PWM speed control Low duty start up function Quick start function Constant voltage output for hall element Lock protection and auto restart (without external capacitor) Rotating speed pulse signal (FG) output and ALARM signal output selectable Applications BD player, Projector, STB etc,. Office equipment, Copier, FAX, Laser Printer, etc,. SSOP-B14 Absolute Maximum Ratings Parameter Symbol Rating Unit Supply Voltage V 30 V CC (Note 1) Power Dissipation Pd 0.87 W Operating Temperature Topr -40 to +105 C Storage Temperature Tstg -55 to +150 C Junction Temperature Tjmax 150 C Output Voltage V 30 V OMAX (Note 2) Output Current I 900 mA OMAX Hall Input Voltage V 7 V H PWM Input Voltage V 7 V PWM SEL Input Voltage V 7 V SEL Signal Output Voltage V 30 V SIG Signal Output Current I 10 mA SIG HB Current Ability I 10 mA HB (Note 1) Reduce by 7.0mW/ over 25. (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.
