Two-phase Unipolar DC Brushless Motor Pre-Driver IC

♦ GENERAL DESCRIPTION

NJM2640 is a two phase unipolar DC brushes motor

pre-driver IC. It features high voltage bipolar technology so

that the driver works up to 48V. High voltage operation

delivers

more

power

and

improves

power

supply

efficiency.Therefore, it is suitable for high voltage fan motor

applications.
