Description

The SMS47 is a nonvolatile user-programmable voltage supply cascade sequencer and supervisory circuit designed specifically for advanced systems that need to monitor multiple voltages.

The SMS47 can monitor four separate voltages without the need of any external voltage divider circuitry unlike other devices that need factorytrimmed threshold voltages and external components to accommodate different supply voltages and tolerances. The SMS47 can also be used to enable DC/DC converters or LDOs to provide a closed loop cascading of the supplies during power-up.

The SMS47 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 programming adapter and Windows GUI software obtainable from Summit Microelectronics.
