INTRODUCTION
The SMS45 is a nonvolatile user-programmable voltage supply cascade sequencer and supervisory circuit designed specifically for advanced systems that need to monitor multiple voltages. The SMS45 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.
FEATURES
● Operational from any of four Voltage Monitoring
