Hej Daniel Rubin. Tack f=F6r ditt meddelande 05:06 2002-11-08 enligt nedan: > There really is no room for an >additional smd transistor let alone 2 diodes. I already have a back-emf >diode across the coil. Remove the back-emf diode, and use a transistor in emitter follwer= configuration. (that will also dissipate the back EMF) =3DNo more= components than today. You will get 1V drop across the tranny though. Another idea Hmmm have i seen a Mosfet with internal zener...? Or select one that= withstand the actual back EMF voltage. /Morgan -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
