The darn H-bridge
February 29, 2008
I just want to be able to reverse a current. How hard can it be?
I just want to be able to decide direction of the motor to my pic, why does it have to be so complicated?
Well - perhjaps it doesnt! Jip / Jimmy, the most clever guy in here just drew me this and send it to me.
The smallest and most-likely-to-burn-something H-bridge in the world!
If it works, I will make a full walkthrough about it.
If it burns my robot.. well.. he did warn me ;)
Transistors are seen from top (usually you see them drawn from below)
Motor will turn one way when
A = low, B = low, C = high, D = high
Other way when A = high, B = high, C = low, D = low
Motor will halt if A = high, B = high, C = high, D = high
... shortcut and smoke if A = low og B = high or C = low and D = high
