i have tried using L298N to control a 12V DC motor which required to drive 1.44A, but i found that the output of L298N that generate to the motor tend to drops to half of the voltage that i supplied to input pin of L298N, and the maximum voltage that manage to supplied to the motor is only achieve around 3V, while i required 7~8V for the motor to lift certain load...anyone have any idea on it???

 

You can increase the power capabilities of the circuit by using external MOSFETs.

 

use amplifier ckt at the output.
