The MAX811TEUS+T is a low-power microprocessor (μP) supervisory circuit from Analog Devices, designed to monitor power supplies in μP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 3V or 5V powered circuits. The device asserts a reset signal when the VCC supply voltage falls below a preset threshold, maintaining it for at least 140ms after VCC has risen above the threshold.
Key features include precision monitoring of 3V, 3.3V, and 5V power-supply voltages, with available reset threshold voltages including 3.08V. The MAX811 has an active-low RESET output, guaranteed to be valid down to 1V. It boasts a low supply current of 6μA, making it ideal for portable equipment. The device is housed in a compact 4-pin SOT-143 package, suitable for surface mounting.
Applications for the MAX811TEUS+T include computers, controllers, intelligent instruments, critical μP and μC power monitoring, and portable/battery-powered equipment. Its integrated voltage monitor increases system robustness with the added manual reset capability. The design offers power-supply transient immunity and saves board space due to its small package and lack of external components.
