I ran into confusion while reading about motors.

Suppose a motor with these specs:

    1. Maximum motor voltage - 6VDC
    2. No load current - 250mA max.
    3. Stall current - around 1A

1) If I use L293D (600mA per channel) to run 1 motor(back and forth), what would happen if my motor requires more than 600mA? or this simply means i need different driver IC?

2) Again, they say if i want to drive 2 motors i'll need to compensate for the current. Is it current from my supply or the driver current?
