l6203
hello all,..
I faced a very huge problem with l6203 in my project and i don't know any solution ,i hope someone can help me to overcome it.
I connected l6203 with atmega32 microcontroller to make a speed control for a dc motor with a two batteries 12 v connected in series to give 24 volt.
The microcontroller takes it's 5 v from a simple regulator 7805.
I used the above circuit for two motors with two h-bridges (l6203) and two microcontrollers each motor has it's microcontroller and h-bridge ( GND and VCC are common for all the circuit).
On connecting the power to the circuit the motors runs normally then suddenly one of the two bridges becomes very hot and then blowing out !!!!!
WHAT IS THE REASON PLEAAASE ??
I am very depressed for that because i don't want the reason for that.
I read l6203 datasheet, i found that there is a table saying that vref taking 13.5 volts typ. is this means that i must connect vref to 13.5 external voltage or what ??
Thanks.
