DESCRIPTION
The DS1238A MicroManager provides all the necessary functions for power supply monitoring, reset control, and memory backup in microprocessor-based systems. A precise internal voltage reference and comparator circuit monitor power supply status. When an out-of-tolerance condition occurs, the microprocessor reset and power-fail outputs are forced active, and static RAM control unconditionally write protects external memory. The DS1238A also provides early warning detection of a user-defined threshold by driving a non-maskable interrupt.
FEATURES
? Holds microprocessor in check during power transients
? Halts and restarts an out-of-control microprocessor
? Warns microprocessor of an impending power failure
? Converts CMOS SRAM into nonvolatile memory
? Unconditionally write protects memory when power supply is out of tolerance
? Delays write protection until completion of the current memory cycle
? Consumes less than 200 nA of battery current
? Controls external power switch for high current applications
? Debounces pushbutton reset
? Accurate 10 power supply monitoring
? Optional 5 power supply monitoring designated DS1238A-5
? Provides orderly shutdown in microprocessor applications
? Pin-for-pin compatible with MAX691
? Standard 16-pin DIP or space-saving 16-pin SOIC
? Optional industrial temperature range -40°C to +85°C
