The MAX811REUS+T is a low-power microprocessor supervisory circuit designed by Analog Devices to monitor power supplies in digital systems. It provides a reliable reset signal when the VCC supply voltage falls below a preset threshold, ensuring system stability.
Key features include a precision monitoring capability for 2.63V power supplies, with a guaranteed reset valid down to 1V for the MAX811 variant. The device asserts a reset signal for at least 140ms after VCC has risen above the reset threshold. It offers an active-low reset output and is designed to ignore fast transients on VCC, increasing system robustness.
This supervisory circuit is ideal for critical μP and μC power monitoring in portable and battery-powered equipment due to its low supply current of 6μA. The MAX811REUS+T comes in a compact 4-pin SOT-143 surface-mount package, saving board space and simplifying power supply requirements. It requires no external components for its core function.
Applications include computers, controllers, intelligent instruments, and other systems requiring reliable power monitoring. The device operates over a temperature range of -40°C to 85°C.
