NTE15006 Integrated Circuit Dual, Bi–Directional Motor Driver Description: The NTE15006 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 motors of various types rated at 6V to 24V. The output voltage can be varied by the use of external zener diodes. This device is especially suited for dual motor drive (reel motor, loading motor, cassette motor in VCR) and for stepping motor drive applications.
