I'm designing a driver circuit for a 12V DC motor (Power Window). I'm using an L293D motor driver chip.
According to the http://www.zartronic.fr/doc/Z1/L293D_ST.pdf the chip can withstand a supply voltage Vs up to 36V. I'm only using a 9V battery.
The circuit and the motor are working well. However, after a few seconds the L293D chip would overheat. If I stop it, it will not work again until it cools down, and if I leave it I'm afraid the chip would be burned
I'm sure there is nothing wrong with my connections because I've redone them many times.
Do you know the reason or the solution to the problem?!
You can get the proper chip connection from http://www.aishack.in/2010/08/simple-motor-driver-circuit/
