Aaaaaand it turns out the datasheet answers all my questions. "The DS2760 returns to Active Mdoe when any of the following occurs: *The PMOD bit has been set to 1 and the SWEN bit is set to 0 and the DQ line is pulled high *The PS pin is pulled low *The voltage on PLS becomes grater than the votlage in VIN with the SWEN bit set to 0 *The pack is enabled through issuance of a SWAP command (SWEN bit = 1) The DS2760 defaults to Sleep Mode when the power is first applied." I should *always* read the datasheet first. I built my circuit based on the Dallas appnote, rather than the datasheet. So I'm adding a switch to pull PS low, and will do that manually first, then via a DS2408 or the like. Thanks for the diagnostic help. *always* read the datasheet first. sheesh. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
