 |  | Hi guys, 
 I built a Hbridge motor driver using the IC
 L298N.  But it is not working properly.  It is
 swithcing properly with the inputs but it is not
 drawing the current required for the motor.  I am
 sensing the out Voltage as 8v but when i connect the
 motor it is dropping to 0v . and the current drawn by
 the motor is very less(0.9ma).   I don't know why it
 is
 not supplying the current for the motors.
 i am giving the circuit as a text attachment.
 Please help me with this. Logically circuit is working
 
 properly, and it is switching the out voltages
 acourding to the inputs but it is not drawing
 sufficiant current from the power source and not
 suppliing to the motors.
 any help is appreciated.
 thank you,
 
 Robo.
