NTE7087 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 Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Maximum Supply Voltage, VCCmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3V to VCC Output Current, IOUT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±1.6A Allowable Power Dissipation, PDmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.2W Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −25° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −55° to +125°C Recommended Operating Conditions: (TA = +25°C unless otherwise specified) Parameter Supply Voltage Symbol Test Conditions Min Typ Max Unit VCC1 7 − 18 V VCC2 5 − 18 V Electrical Characteristics: (TA = +25°C, VCC = 12V unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Input Threshold Voltage Vth RL = ∞ 1.1 1.3 1.5 V Minimum Input ON−State Current IIN RL = ∞ − 10 15 μA Output Voltage VO RL = 60Ω, VZ = 7.4V 6.6 7.2 7.4 V Output Leakage Current IOL Pin5, Pin6 GND, RL = ∞ − 0.01 1.0 mA Current Dissipation ICC Pin5, Pin6 GND, RL = ∞ 3 6 10 mA VCC = 12V, IOUT = 300mA − 1.9 2.2 V VCC = 12V, IOUT = 500mA − 1.9 2.3 V VCC = 12V, IOUT = 300mA − 0.25 0.5 V VCC = 12V, IOUT = 500mA − 0.4 0.65 V Saturation Voltage (Upper) Vsat1 Saturation Voltage (Lower) Vsat2 Truth Table: Input Output Operation IN1 IN2 OUT1 OUT2 0 0 0 0 Braking 1 0 1 0 Forward (Reverse) Drive 0 1 0 1 Reverse (Forward) Drive 1 1 0 0 Braking Input Level 1: 2.0V or greater 2: 0.7V or less Pin Connection Diagram (Front View) 10 Out 2 9 P2 8 VCC2 7 VCC1 6 In 2 5 In 1 4 VZ 3 P1 2 Out 1 1 GND .992 (25.2) .110 (2.8) .326 (8.28) Max .100 (2.54) 1 10 .019 (0.48) .900 (22.8) .118 (3.0) Min
