LB1649中文资料三洋数据手册PDF规格书

Overview

The LB1649 is a dual bidirectional motor driver. Since each channel has a 2-input logic circuit and performs bidirectional driving and braking functions, it is capable of direct driving 2pcs. of motor of various types rated at 6 to 24V.

The output voltage can be varied by using external zener diodes.

It is especially suited for dual motor drive (reel motor, loading motor, cassette motor in VCR) and for stepping motor drive.

特性 Features

• Performs braking function at the motor stop mode.

• Contains elements to absorb motor dash current.

• Input connectable dirct to MOS LSI.

• Minimun number of external parts required.

• Wide operating voltage range.
