I'm trying to build a motor driver which can supply ~3A per motor. Only cheap IC I could get my hands on was L298, so I decided to parallel its channels. But for some reason that I can't understand (I'm merely an amateur hobbyist), L298 and its diodes are getting too hot in just a matter of seconds.
I'm using a 12V (max 40W) power supply for my circuit, and its reduced to 0.95V when I check VCC/GND pins (how is that even possible ?)
This is my PCB design.
