Brushed DC motors and motor drivers
Benta:
There's no reason to design for maximum stall current. It's normal to limit start-up/locked-rotor current for DC motors.
The main suppliers for DC motor ICs are Toshiba and TI:

Never heard of the TA6586.

Received the TA6586 a while back, but had other things on my mind that needed attention first.
It looks promising. Have to do some more tests and modify my receiver PCB to test it on that to make sure it will do.
By the looks of it the ic has build in current limiting and acts on it. Need to test it with a smaller motor to see if this is actually the case. One thing is for sure, it does need the decoupling capacitor. For my first simple test I omitted it and I noticed hefty oscillation on the power supply line. :palm:
