# L298N Module Out 1 and Out 2 failure

I have an L298N motor controller module, rated at 5 amps. I'm using it to control two 12 volts linear actuators, and I'm using a current sensor per motor to learn when the motors have reached a high current load (~2.26 Amps) then stop them once they reach that threshold.

One of the actuators shaft bent on an accident, and now it requires 3.4 Amps (instead of the 0.9 Amps "no load" current) to move. The thing is that the current draw never goes above my threshold, as measured by my current sensor (therefore, the actuator never moves when a signal is sent). But now the channels (Out 1 and Out 2) on the L298N where the bent actuator was connected to don't work properly:

when nothing is connected to those two channels, I read and output closed to 12V.
But as soon as I plug in any motor on those two channels
(whether good or bad), those channels send 0V.


What exactly could have caused the failure of these channels? And is it a short that might have happened and something burned?

• Try a power resistive load at 1A then 2A etc to find the cause – user51925 Sep 5 '14 at 22:16
• Try adding a circuit. – Andy aka Sep 5 '14 at 22:35

This will likely lead to early failue of the L298 - respect the data sheet. For $t_{on}$ of 10 msecs you can go as high as 2.5 amps - are you adhering to this?
