MAX6354TYUK+T

The MAX6354TYUK+T is a dual voltage microprocessor (µP) supervisory circuit in 5 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. In addition, the outputs are valid as long as either input supply voltage remains greater than +1V. The output reset state is guaranteed to remain viable while either VCC1 or VCC2 is above +1V. This device is used in computers, controllers, portable/battery powered equipment, intelligent instruments and multivoltage systems.

• Supply voltage range is 1.2V to 5.5V at TA = -40°C to +85°C, 1V to 5.5V at TA = 0°C to +70°C
• Operating temperature range from -40°C to 85°C
• Precision monitoring of multiple +1.8V, +2.5V, +3V, +3.3V and +5V power supply voltages
• Precision factory set power supply reset thresholds
• Supply current is 20µA, reset timeout period of 180ms
• Active-low debounced manual reset input
• Active-low push-pull reset output referenced to VCC2
• Minimum power-on-reset pulse width is 100ms, power supply transient immunity
• 3.08V VCC1 nominal voltage threshold, 2.19V VCC2 nominal voltage threshold
• Low cost, no external components for dual voltage systems
