NTE1774
Integrated Circuit
Dual, Bi–Directional Motor Driver
Description:
The NTE1774 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.
Features:
D Able to Withstand 1A (Max) Dash Current with Contained Motor Drive Power Transistor
D Performs Braking Function at the Motor Stop Mode
D Contains Elements to Absorb Motor Dash Current
D Direct Input Connection for MOS LSI
D Minimum Number of External Parts Required
D Wide Operating Voltage Range
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
