Any australian sources?
Jaycar sales staff didn't even know what a h bridge was.

10-20Amps in anything is not something they normally stock.Jaycar sales staff didn't even know what a h bridge was.
you would have to go to a stockist of the item that you are building.

Just a couple of questions for you...
What do you need it to do? ie. do you require overcurrent shutdown, soft
start/stop, regen braking, position control etc...... or just a basic
h-bridge and you will implement required features yourself?
How many units do you require?
Regards
James

I am using a K8055 interface board.
I have a basic understanding of analog

likely end up building my own h-bridge
using mosfets but thought I should try
first for a possible Australian source
of a ready built product in case the
price was reasonable.
Thanks to everyone for your responses.

RS Components have a good range of MOSFET drivers, whch include half-bridge
drivers in DIP-8 packages. They can drive N-channel power FETS directly, and
allow the top device to be supplied from quite high voltages (up to hundreds
IIRC). They also handle the switchover correctly so oyu don't get transient
shorts across the rails and consequent transient problems.
I bought a few a while back for a power square wave driver, the pricess were
surprisingly reasonable for a small quantity.
