This post describes for the semiconductor L2930NE.
The function of this semiconductor is quadruple high-current half-H driver.
The Correct Part number of L2930NE is L293DNE.
The manufacturer of this part is Texas Instruments.
See the preview image and the L2930NE Datasheet PDF file for more information.
The L293 and L293D devices are quadruple high-current half-H drivers. The L293 is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
