Формирователи импульса сброса MAX6714AUB+

Схема контроля микропроцессора , 4 монитора, 2В-5.5В питание, выход сброса с активным низким

The MAX6714AUB+ is a low voltage, high accuracy, quad voltage monitor in 10 pin µMAX package. It is mainly designed for multivoltage systems. The quad voltage monitors provide accurate monitoring of four supplies without any external components. The quad voltage monitor includes an accurate reference, four precision comparators and a series of internally trimmed resistor-divider networks. The high input impedance comparator option can be used as adjustable voltage monitor, general purpose comparator or digital-level translator. The MAX6714 provides an active-low, open-drain RESET(complementary) output with integrated reset timing and three power-fail comparator outputs.
