Subject: [alt-beam] H-Bridge
Hi!
For my first Walker I used a 74ALS245 motor driver, and for my next one I
plan to use H-Bridges.
I found 2 differents shematics on different web sites:
the first one with 2 PNP transistors and 4 NPN transistors
and the other one with 4 PNP transistors, 2 NPN transistors and a .47 uF
capacitor.
Also, I remember that I read someting about a H-Brigde using only 4
transistors.
So, can someone explain me what are the differences between these
H-Bridges, like current or other things that are useful to know?
Thank you
Martin
