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

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.
