INTRODUCTION

The SMS44 is a highly programmable voltage supervisory circuit designed specifically for advanced systems needing 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.
