I tried it with a two cell LiPo (8,4V at max charge) directly for the motor and 5V for dspic, and it works fine. So, I think it can also do the job with 9V, but look for absolute max. in datasheet, I do not remember what the value it was. 2012/5/30 Josh Koffman > On Tue, May 29, 2012 at 3:15 PM, Vicent Colomar Prats > wrote: > > As a driver for small motors you can use mcp14e4 or similars.
