L293DNE Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the motor is 36V, which is the maximum rating of the L293DNE. However, it's recommended to operate within 24V to ensure reliable operation.
  • To protect the L293DNE from back-EMF, you can add a flyback diode (also known as a freewheeling diode) in parallel with the motor. This diode absorbs the back-EMF and prevents it from damaging the L293DNE.
  • The maximum current that the L293DNE can handle is 1A per channel, with a peak current of 2A. However, it's recommended to operate within 0.5A to ensure reliable operation and prevent overheating.
  • The L293DNE has an enable input (EN) that allows you to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled.
  • VCC1 is the power supply for the logic circuitry, and VCC2 is the power supply for the motor driver. Typically, VCC1 is connected to a 5V supply, and VCC2 is connected to the motor voltage (up to 36V).
