OVERVIEW
The SMS29xx is a power supervisory circuit that monitors
V
CC
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
interface allowing quick implementation in an end-users’
system.
