NTE7064
Integrated Circuit
Bridge Driver for DC Motor Control
Description:
The NTE7064 is an integrated circuit in a 7−Lead SIP type package designed for use as a bridge driver
for brushed DC motor rotation control. Forward rotation, reverse rotation, stop, and braking operations are available. Typical applications include a loading and reel motor driver for VCR and tape
deck, and any other consumer and industrial applications.
Features:
D Output Current Up to: 1 Amp (Average), 3 Amp (Peak)
D 4 Function Modes (CW, CCW, STOP, and BRAKE) are Controlled by 2 Logic Signals Fed Into
2 Input Terminals
D Built−In Over Current Protection and Thermal Shut−Down Circuit
D Operating Voltage Range: VCC = 6V to 18V
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
