The MAX6355SYUT+T from Maxim Integrated Products is a triple voltage microprocessor (µP) supervisory circuit in 6 pin SOT-23 package. This µP supervisory circuit maintains system integrity by alerting the µP to fault conditions. The microprocessor (µP) supervisor with multiple reset voltages significantly improves system reliability and accuracy compared to separate IC"s or discrete components. If any input supply voltage drops below its associated preset threshold all reset output is asserted. The output reset state is guaranteed to remain viable while either VCC1 or VCC2 is above +1V. It has active-low debounced manual-reset input and an additional voltage monitor input to monitor a third voltage. This device is used in computers, controllers, portable/battery powered equipment, intelligent instruments and multivoltage systems.
