Hello,

I'm trying to build a T.E.N.S. Circuit that was featured in a Silicon Chip magazine issue a couple of years back. It uses an MC3406? DC-DC converter supplying IR2155 Half bridge driver to drive two IR 610 Mosfets for high side and low side. The circuit is for only one channel I wanted to add another. Can I just add another Half bridge driver and pair of mosfets? and will they be isolated from each other? or do I need to use a transformer, so that the channels don't have a common ground?

I appreciate any help I can get. Thanks

 

bump......

 

Just a quick verbal explanation isn't quite enough information.

Post the circuit.

 

My apologies... here is the circuit.

 

What is a T.E.N.S unit?

 

T.E.N.S. Is short for trans-cutaneous electrical nerve stimulation. It helps to alleviate pain by over stimulation of pain receptors in the affected area so that they can't transmit a pain signal to the brain.

 

OK, thanks. I'll let folks a bit more familiar with MOSFETs answer this one.
