Формирователи импульса сброса MAX6352LSUK+T

Схема контроля микропроцессора , 2 монитора, 1.2В-5.5В питание, выход сброса с активным низким

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
