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 = +25C unless otherwise specified) Supply Voltage, VCC Peak . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Current, IO Average . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1A Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3A Power Dissipation (TC = +75C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12.5W Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Electrical Characteristics: (TA = +25C unless otherwise specified)
