NTE7087

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 VCC1 VCC2 Test Conditions Min 7 5 Typ − − Max 18 18 Unit V V Electrical Characteristics: (TA = +25°C, VCC = 12V unless otherwise specified) Parameter Input Threshold Voltage Minimum Input ON−State Current Output Voltage Output Leakage Current Current Dissipation Saturation Voltage (Upper) Saturation Voltage (Lower) Symbol Vth IIN VO IOL ICC Vsat1 Vsat2 RL = ∞ RL = ∞ RL = 60Ω, VZ = 7.4V Pin5, Pin6 GND, RL = ∞ Pin5, Pin6 GND, RL = ∞ VCC = 12V, IOUT = 300mA VCC = 12V, IOUT = 500mA VCC = 12V, IOUT = 300mA VCC = 12V, IOUT = 500mA Test Conditions Min 1.1 − 6.6 − 3 − − − − Typ 1.3 10 7.2 0.01 6 1.9 1.9 0.25 0.4 Max 1.5 15 7.4 1.0 10 2.2 2.3 0.5 0.65 Unit V μA V mA mA V V V V Truth Table: Input IN1 0 1 0 1 IN2 0 0 1 1 0 1 0 0 Output OUT1 OUT2 0 0 1 0 Braking Forward (Reverse) Drive Reverse (Forward) Drive Braking Operation 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 .110 (2.8) .992 (25.2) .326 (8.28) Max 1 10 .100 (2.54) .019 (0.48) .900 (22.8) .118 (3.0) Min
