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
Power DMOS FET integrated
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

(Note 1) Reduce by 7.0mW/℃ over 25℃. (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.
