Формирователи импульса сброса MAX16008TP+

Схема контроля микропроцессора , 4 мониторов, 1В-5.5В питание, выход сброса с активным низким

The MAX16008TP+ is a low voltage, high-accuracy, quad window voltage detector in 20 pin TQFN package. It is designed to provide a higher level of system reliability by monitoring multiple supply voltages and providing a fault signal when any of the voltages exceed their overvoltage thresholds or fall below their undervoltage thresholds. The user-adjustable thresholds allow voltages to be monitored down to 0.4V. It allows the upper and lower trip thresholds of each window detector to be set externally with the use of three external resistors. Each monitored threshold has an independent open drain output for signalling a fault condition. The outputs can be wire OR'ed together to provide a single fault output. The open-drain outputs are internally pulled up with a 30µA current, but can be externally driven to other voltage levels for interfacing to other logic levels. It feature a margin input to disable the outputs during margin testing or any other time after power-up operations.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to 125°C
• Monitor four undervoltage
• overvoltage conditions
• 1.5% accuracy over temperature
• Output logic state down to VCC = 1V
