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) Supply Voltage, VCC Peak . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Current, IO Average . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1A Operating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3A Power Dissipation (TC = +75°C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12.5W Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −30° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −55° to +150°C Electrical Characteristics: (TA = +25°C unless otherwise specified) Parameter Supply Current Symbol Test Conditions Min Typ Max Unit ICC1 VCC = 18V, Output OFF, Stop Mode − 1.8 3.5 mA ICC2 VCC = 18V, Output OFF, CW/CCW Mode − 8.3 12.0 mA ICC3 VCC = 18V, Brake Mode − 8.5 13.0 mA Electrical Characteristics (Cont’d): (TA = +25°C unless otherwise specified) Parameter Saturation Voltage Symbol Upper VS1 U Lower VS1 L Upper VS2 U Lower VS2 L Output Transistor Leakage C Current t Upper IL U Lower IL L Input Voltage IN 1 VIN (H) IN 2 VIN (L) Diode Forward Voltage Test Conditions VCC = 18V, IO = 100mA VCC = 18V, IO = 1A V = 25V TJ = +25°C, Pin1 and Pin2 IF = 1A Min Typ Max Unit − − 1.1 V − − 1.0 V − 1.2 1.5 V − 1.05 1.4 V − − 50 μA − − 50 μA 3.0 − − V − − 0.8 V − 2.0 − V Upper VF U Lower VF L − 1.3 − V Limitting Current ISC − 2.5 − A Input Current 1, 2 IIN 1,2 − 1 30 μA TJ = +25°C, Pin1 and Pin2 Block Diagram VCC IN1 1 IN2 2 7 6 VS CONTROL 3 OUT1 5 OUT2 4 GND THERMAL PROTECT OVER CURRENT IN 1 IN 2 OUT 1 OUT 2 MODE 1 1 L L Brake 0 1 L H CW/CCW 1 0 H L CCW/CW 0 0 High Impedance Stop Pin Connection Diagram (Front View) 7 VCC 6 VS 5 OUT2 4 GND 3 OUT1 2 IN2 1 IN1 .681 (17.3) Max .118 (3.0) .641 (16.3) Max .125 (3.2) Dia .638 (16.2) .504 (12.8) 1 7 .209 (5.5) Min .100 (2.54)
