Making a DC motor driver with H-Bridge technique can use IC L293D as in the article "DC Motor Driver H-Bridge L293 (2 Motor DC)"is. DC motor driver L293D can be used to control the DC motor 2 pieces at once. DC Motor Driver L293D can be used to control a DC motor continuously or with a PWM technique. Dc motor driver circuit in the article "DC Motor Driver H-Bridge L293 (2 Motor DC)" only use IC L293D only. For more details see the following figure. Working system of DC motor driver L293D is to provide control signals in the form of logic or pulse to the input lines 1A - 1B for DC motor control M1 and the input 2A - 2B for the control of DC motor M2 with the following conditions: Input A Input B Motor DC 0 0 Motor silent 1 0 motor rotates counterclockwise 0 1 Motor berputer clockwise 1 1 Motor silent Description: Enable Input given a logic 1 to obtain such data in the table above.

Build a 15W Bridge Audio Amplifier Circuit based TDA2002. 15W bridge audio amplifier circuit which use 2 pieces of TDA2002. This is audio amplifier for general, work with a single power supply. Use 2A power supply transformer for maximum performance and heatsink should be used to keep the IC from overheating. Build a 15W Bridge Audio Amplifier Circuit based TDA2002 Component part list: R1-5 = 2.7? R2 = 100? R3-4 = 2.2? R6 = 220? R7 = 1M? TR1 = 100K? trimmer C1-9 = 10uF/16V C2-8 = 220uF/16V C3-4-5-7 = 100nF/63V C6=470uF/25V IC1-2=TDA2002 Lsp = 4 – 8?/40W Loundspeaker

The afterward diagram is 16W Bridge audio amplifier circuit. The ambit congenital based 2 pieces of ability IC LM383 in arch connection, so this amplifier is an arch amplifier. This is an old amplifier, LM383 is discontinued, so this LM383 ability be difficult to find. You can use ECG1232, TDA2002 or TDA2003 as the alter for LM383. Take a agenda that a heatsink bowl is appropriate to abstain overheating on the ICs.
