The MAX811TEUS+T from Analog Devices is a low-power microprocessor (μP) supervisory circuit. It is designed to monitor power supplies in μP and digital systems, providing excellent circuit reliability and low cost by eliminating external components. This device asserts a reset signal when the VCC supply voltage falls below a preset threshold, maintaining the signal for at least 140ms after VCC has risen above the threshold.
Key features include precision monitoring for 3V, 3.3V, and 5V power-supply voltages, a minimum power-on reset pulse width of 140ms, and immunity to power-supply transients. It operates with a low supply current of 6μA, making it ideal for portable equipment. The MAX811TEUS+T comes in a compact 4-pin SOT-143 surface-mount package.
Applications for this supervisory circuit include computers, controllers, intelligent instruments, critical μP and μC power monitoring, and portable/battery-powered equipment. It offers integrated voltage monitoring and an added manual reset function, increasing system robustness. The reset comparator is designed to ignore fast transients on VCC.
