The MAX811MEUS+T is a low-power microprocessor supervisory circuit designed by Maxim Integrated to monitor power supplies in microprocessor and digital systems. It provides a reset signal when the VCC supply voltage drops below a preset threshold, maintaining the reset for at least 140ms after VCC has risen above the threshold. This device features a precise monitoring of 3V, 3.3V, and 5V power-supply voltages with a reset threshold of 4.38V.
With a low supply current of 6μA, the MAX811MEUS+T is ideal for portable and battery-powered equipment. It operates over a temperature range of -40°C to 85°C and comes in a compact 4-pin SOT-143 package, saving board space. The supervisory circuit offers power-supply transient immunity and includes a debounced manual reset input.
Applications for this supervisory circuit include computers, controllers, intelligent instruments, and critical μP and μC power monitoring. Its integrated voltage monitor and manual reset enhance system robustness.
