Subject: [alt-beam] Re: MOTOR DRIVER QUESTION
It depends on what you planning to do with it.
A H-bridge is more like a standard all use workhorse. Often it is overkill
for the task you want it to do. A Z-bridge and a 240 chip is only suitable
for low current apps otherwise you have to stack them. This will produce
nice little driver packages and cheap too.
