General Description
SMS48 General Description
The SMS48 is a highly programmable voltage supply controller and supervisory circuit designed specifically for advanced systems that need to monitor multiple voltages.
The SMS48 can monitor four separate voltages without the need of any external voltage divider circuitry. This alleviates the need for factory-trimmed threshold voltages and the use of external components to accommodate different supply voltages and tolerances.
The SMS48 has four programmable independant reset outputs to control different devices for varying reset conditions such as UV, OV, watchdog and user pushbutton applications.
The SMS48 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 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 Summit Microelectronics.
