The MAX811SEUS-T from Analog Devices is a low-power microprocessor supervisory circuit designed for monitoring power supplies in digital systems. It provides a reset signal that asserts when the VCC supply voltage drops below a preset threshold of 2.93V, maintaining the reset for at least 140ms after the voltage recovers.
This device features an active-low reset output and is ideal for critical μP and μC power monitoring applications. It offers excellent circuit reliability and low cost by eliminating external components. The reset comparator is designed to ignore fast transients on VCC, enhancing system robustness.
The MAX811SEUS-T operates over a temperature range of -40°C to 85°C. It is housed in a compact 4-pin SOT-143 surface-mount package, making it suitable for space-constrained portable and battery-powered equipment.
Key specifications include a single monitored voltage, an active-low push-pull output, and a typical supply current of 6μA. This supervisor IC is designed for precision monitoring of 3V, 3.3V, and 5V power-supply voltages.
