DC Motor Speed and direction controller project based on L293D H-Bridge and 555 Timer IC. 555 Generate PWM and L293D works as output driver. The 293D provides bidirectional drive current up to 600mA a voltage from 5V to 12V. L293D includes the output clamping diodes for protections.
- Supply 5 to 12 V
- Inhibit facility/enable
- PWM Frequency 5KHz Maximum
- High Noise immunity
- Over temperature protection
- Capable of delivering output current up to 600 mA per channel
