In a similar application Russell had advised me to use 10R series to the gate and 270R pulldown (for N-ch) + a 15V ZD, as well as using active drives, for both low and high (in an N/P bridge) to get around the gate capacitance Are those 1N5819s going to be tough enough ? 1N5820 3A ? I went for the PBYR745 (7.5A TO220, but I'm running more than your 1A) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
