The MAX811LEUS-T is a low-power microprocessor supervisory circuit designed by Analog Devices Inc. (Maxim Integrated) to monitor power supplies in digital systems. It features a precision monitoring of 4.63V power-supply voltage and asserts an active-low reset signal when the VCC supply voltage falls below this threshold. The reset signal is held asserted for at least 140ms after VCC has risen above the reset threshold, ensuring system stability.
This device is ideal for critical μP and μC power monitoring applications, especially in portable and battery-powered equipment due to its low supply current of 6μA. It offers power-supply transient immunity and requires no external components. The MAX811LEUS-T comes in a compact 4-pin SOT-143 surface-mount package, making it suitable for space-constrained designs.
Key features include guaranteed operation over temperature and a reset valid down to 1V for the MAX811 variant. The supervisory circuit ignores fast transients on VCC, enhancing system robustness. It is designed for use with 3V, 3.3V, and 5V powered circuits.
