    pic 16F877A is always burning when i used it in LIGHT TRACKER CAR

    the 2 DC motor will take all this voltage even to overcome initial condition so i think the Voltage remaining is (2.5 -4v ) so the Microcontroller is working only for 3 mn otherwise the Microcontroller is burning quickly and never working i believe the problem is with ic L 293 D motor driver...
