OVERVIEW

The SMS29xx is a power supervisory circuit that monitors

and will generate complementary reset outputs. The

reset pins also act as I/Os and may be used for signal

conditioning. The SMS29xx also has an on-board watch-

dog timer.

The SMS29xx integrates a nonvolatile serial memory. It

features the industry standard I

C serial

interface allowing quick implementation in an end-users’

system.
