DC Brushless Fan Motor Driver

Standard Single-phase Full wave

Fan motor driver

BD6964FVM

Description

This is the summary of application for BD6964FVM. BD6964FVM can drive FAN motor silently by BTL soft switching, and it

can control rotational speed by PWM signal.

Features

■ Compact package (MSOP8)

■ 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.

(Note 1) Reduce by 4.68mW/°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.
