Your memory serves you well, found something called a TPIC5403 which consists of 4 independent DMOS FET's in a single package. Unfortunately, the TI website says it's obselete and it hasn't been produced in years. As for the rest of TI's offerings, all low-side drivers, every last one. -- pete@petertodd.ca http://www.petertodd.ca -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
