Title: Ask L298
Post by: hendrachubby on April 17, 2009, 06:23:55 PM

Hallo ALL, i need help

I got trouble to using L298 motor driver, for higher current i paralleled the outputs just like in the datasheet. I use atmega16 microcontroller to give the logic (input 1 and input 2) and PWM pulse (enable), maybe i miss something important when designing the board so i attach my schematic, thx

in the schematic, the sen_a and sen_b pins arent connected anywhere. These need to be at least connected directly to GND
