Original Information link was no good , uploaded file
in Files section of this group.
I was researching for a bipolar stepper control chip
for a homebrew CNC controller .
These chips I found are discontinued but have great features
BiPolar Chopping Half/Full Steps ,for external H Bridge Circuit
and current sensing for current control. One for each motor
They are PBL3776QN (28-pin PLCC) ,same as PBL3776 but different
socket.
I bought some commercial units yesterday ,but I would like to
get a few of these for myself for future experiments.
I have to order at least 10 at a time , I only want 4 or 5 for myself.
They are $16.00 each ,any quantity as long as my minimum
order reaches "10" , up to 450 available for immediate shipment .
I was quoted for the same chip $27.00 from another chip broker.
$16.00 each is a lot better ;-) ,price includes postage.
Continental US
No Offshore sales ,sorry ,unless somebody here buys them
and takes care of the shipping
Here is the info packet for this chip, it is the same chip
NJR bought this Ericcson line and then discontinued it.

Anybody wants to order ,email me sspeed@...
PayPal accepted same as my email ,money orders as well , no checks
I can get first batch ordered on Monday. Then I'll see about going
further.
I am not offering any warranty ,its up to you how you use them
and design your circuits.
I think I covered it all.
Thanks
