#97159 - I'm designing a similar one Responding to: ???'s previous message |
Hi,
a untested circuit posted here 
in the circuit 555 is used as a schmitt trigger as opto output is slow.LM555 output rise/fall time is 100ns. LM555 can source and sink 200 mA. This is required to quicly charge or discharge the gate capicitances. Abhishek |
