Post by: mohit sharma on October 06, 2009, 10:17:20 AM

i want to connect a dc motor with L298N . Please help me i cant understand pin description in datasheet . What does current sensing, enable and logic supply pin means.

Hi,

Logic supply is the voltage that drives the logic/microcontroller - usually 5V or 3.3V,
Current sensing is well... Sensing the current through the motor (driven by a higher voltage than your logics) to keep a max. on the current. If eg. a stepper motor is used, this keeps it from burning the windings at stand still (if properly calculated).
