Формирователи импульса сброса MAX6342LUT+T

Схема контроля , ручной, двухтактный, 1В - 5.5В, 4.63В порог, 180мс задержка, SOT-23-6

The MAX6342LUT+T from Maxim Integrated Products is a microprocessor (µP) reset circuit with power-fail comparator in 6 pin SOT-23 package. This microprocessor (µP) supervisory circuit monitors power supplies in digital systems. This device is significantly improves system reliability and accuracy compared to separate ICs or discrete components. It provides factory trimmed VCC reset threshold voltage and operate with supply voltages between +1V and +5.5V. A +1.25V threshold detector allows for a power-fail warning, for low-battery detection or for monitoring another power supply. The MAX6342 contains an MR (active low-MANUAL-RESET) input and an active-low push-pull reset. It is ideally used at portable computers, telecom equipment, networking equipment, portable/battery-powered equipment, multivoltage systems and embedded control systems.
