FEATURES
INTRODUCTION
The SMS44 is a highly programmable voltage supervisory
circuit designed specifically for advanced systems need-
ing to monitor multiple voltages. The SMS44 can monitor
four separate voltages without the need of any external
voltage divider circuitry
The SMS44 watchdog timer has a user programmable
timeout period and it can be placed in an idle mode for
system initialization or system debug. All of the functions
are user accessible through an industry standard 2-wire
serial interface.
