IPS3313 was: Wooden CNC router
2006-12-09 by Curtis Richards
Hi All, If you are building a CNC mill or a robot you might want to look into International Rectifier's IPS3313 intelligent switch. It will handle 45 amps and 32 volts and has built in thermal and current limiting in a 5 pin TO-220 package. I've been using them as an injector driver with a Megasquirt EFI clone on my !950 Jeepster F-head ( don't ask! ) without a hitch where IGBTs have had a nasty tendency to let the 'blue smoke' out. The best news is that they are $5.05 US in singles or $3.79 for 50 on the IRF samples website. https://ec.irf.com/v6/en/US/adirect/ir?cmd=MultiplePriceAvailabilityDisplay&ShoppingCartKey=936388 <https://ec.irf.com/v6/en/US/adirect/ir?cmd=MultiplePriceAvailabilityDisplay&ShoppingCartKey=936388> -- Curtis W Richards -- "The universe is nothing but atoms and empty space, all else is opinion" Diogenes Laertius
