NTE7091
Integrated Circuit
Dual, Bi–Directional Motor Driver
Description:
The NTE7091 is an integrated circuit in a 10–Lead SIP type package designed for forward/reverse
direction select driver by switching motor 1 or motor 2 with a brush. Forward/reverse direction select
of motor 1 or motor 2 can be made by 3–bit input logic. It also assures five outputs of both brakes
and is suitable for VCR tape loading and cassette loading, video disc players, etc.
Features:
D Wide Range of Operating Supply Voltage: V_CC(opr) = 4V to 20V
D Forward and Reverse Drive of Motor 1 or Motor 2 by 3–Bit Input.
D Built–In Thermal Protection Circuit.
