Integrated Circuit
Bi−Directional Motor Driver
Description:
The NTE7087 is a bi−directional motor driver IC in a 10−Lead SIP type package capable of direct driving
6V, 9V, and 12V motors. This device has a 2−input logic circuit and performs the functions of bi−directional driving and braking. The output voltage can be varied by using an external zener diode.
Features:
D 2−Input Logic can be used to Excercise Control of Bi−Directional Driving and Braking
D On−Chip Elements to Absorb the Dash Current of the Motor
D Input Interfaceable with MOS LSI
D Output Voltage Variable by using an External Zener Diode
