The MAX6352LSUK+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. The output reset state is guaranteed to remain viable while either VCC1 or VCC2 is above +1V. This device is used in computers, controllers, intelligent instruments and multivoltage systems.
Supply voltage range is 1.2V to 5.5V
Operating temperature range from -40°C to 85°C
Precision monitoring of multiple +1.8V, +2.5V, +3.0V, +3.3V and +5V power supply voltages
Precision factory set power supply reset thresholds
Supply current is 20μA
Manual reset input
Active-low open drain reset output
Minimum power-on-reset pulse width is 100ms, power-supply transient immunity
Debounced TTL/CMOS compatible, fully guaranteed over temperature
Low cost, no external components for dual-voltage systems
