OVERVIEW
The SMS29xx is a power supervisory circuit that monitors VCC 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 watchdog timer.
The SMS29xx integrates a nonvolatile serial memory. It features the industry standard I2C serial interface allowing quick implementation in an end-users’ system.
