Формирователи импульса сброса MAX6710DUT+T

Схема контроля , активный низкий, открытый сток, 4 монитора, 2В - 5.5В, 200мс задержка, SOT-23-6

The MAX6710DUT+T from Maxim Integrated Products is a low-voltage, high-accuracy, quad voltage µP supervisory circuits in 6 pin SOT-23 package. This precision quad voltage microprocessor (µP) supervisory circuits monitor up to four system supply voltages and assert a single reset if any supply voltage drops below its preset threshold. This device significantly reduce system size and component count while improving reliability compared to separate ICs or discrete components. A single active-low output asserts when any monitored input falls below its associated threshold. The open-drain output has a weak internal pull-up (10µA) to IN2. For the MAX6710, reset remains low for the reset timeout period (140ms min) after all voltages rise above the selected threshold. It is used in telecommunications, high end printers, desktop and notebook computers, data storage equipment, networking equipment, industrial equipment, set-top boxes and servers/workstations.

• Supply voltage range is 1.2V to 5.5V

• Low 35µA supply current
• Open drain RESET(active-low) output with 10µA internal pull-up
• RESET(active-low) valid to IN1 = 1V or IN2 = 1V
• Immune to short monitored supply transients
• Monitors three fixed voltages 5V, 3.3V, 1.8V and an adjustable voltage
• Adjustable voltage threshold monitors down to 0.62V with 1.5% accuracy
• Supply voltage tolerance is 5%
