Hi,
I'm driving a mosfet H-bridge with an lm339 in a schematic somehow similar to this one http://letsmakerobots.com/node/18633 .
For current limiting, I thought about switching off the power (Vcc) on the lm339 whenever over current happens. Is it a good idea, or does the lm339 need some time when powered up to stabilize?
I don't want to bother the μC with over current limitating.
Thank you.
