The SMS45 can monitor four separate voltages without the need of any external voltage divider circuitry unlike other devices that need factory- trimmed threshold voltages and external components to accommodate different supply voltages and tolerances. The SMS45 can also be used to enable DC/DC converters or LDOs to provide a closed loop cascading of the supplies during power -up. The SMS45 watchdog timer has a user programmable time-out 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 I2C 2-wire serial interface. Programming of configuration, control and calibration values by the user is simplified with the SMX3200 interface adapter and Windows GUI software obtainable from Sum- mit Microelectronics.
