Thanks everyone for all the suggestions. I neglected to explain why I had to drive FETs - I'm controlling astroflight cobalt motors that draw up to 30 amps, so most single chip solutions wont work unless several are run in parallel. I just ordered a few of the Micrel parts as Andy suggested ( MIC5022 ). These half bridge drivers meet the gate drive requirements and as a bonus, have current sense and overcurrent disconnect capability built in. -Nicholas -----Original Message----- From: Andy Kunz To: PICLIST@MITVMA.MIT.EDU Date: Friday, July 23, 1999 11:17 AM Subject: Re: Driving a high voltage H-bridge from a PIC >>So far, the only suitable driver I have found is the IR2110 from >>International Rectifier.
