| NTE7042 Integrated Circuit Bi-Directional Motor Driver Description: The NTE7042 is a Bi-Directional Motor Drive in a 9-Lead SIP type package and generates an output current of 700mA (Max) with 4 output modes of forward rotation, reverse rotation, stop (idling), and brake according to input logic (2 inputs). The GNDs of the logic unit and power unit are isolated. Therefore, the circuit of a reversible, variable-speed motor can be easily composed by adding an electronic governor at the output. Features: D Built-in Surge Absorbing Diode D Low Standby Current D Wide Operating Voltage Range: 4.5V to 15V D TTL Compatible D Built-in Thermal Shutdown Circuit Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supplu Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Current, IO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 700mA Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8mW/C Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +60C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Electrical Characteristics: (VCC = 9V, TA = +25C unless otherwise specified) Parameter Supply Voltage Supply Current Symbol VCC1 VCC2 ICC1 ICC2 Standby Current High Level Input Voltage Low Level Input Voltage High Level Input Current Collector-Emitter Voltage Istandby VIH VIL IIH VCE VIN = 2V IO = 200mA Test Conditions VCC (Pin6) GND (Pin2, Pin5) VCC (Pin6) COM (Pin8) Pin1 "H", Pin3 "L" or Pin1 "L", Pin3 "H", RL = Pin1 "H", Pin3 "L", RL = Pin1 "L", Pin3 "L" Min 4.5 4.0 18 34 - 2.0 - - - Typ Max Unit - - 34 52 - - - 93 1.2 15 15 50 70 1.5 - 0.8 135 1.6 V V mA mA mA V V A V Truth Table: Input (Pin3) L H L H Input (Pin1) L L H H Output (Pin7) Open H L L Output (Pin9) Open L H L IC not Operating Motor Forward Motor Reverse Brake Note 1.
