The MAX811REUS+T is a low-power microprocessor (µP) voltage monitor with a manual reset input, housed in a 4-pin SOT-143 package. It is designed to supervise power supplies in µP and digital systems, providing reliable operation with minimal external components. The device features an active-low push-pull RESET output that must be in the correct state for VCC down to 1V. It offers precise monitoring of 3V, 3.3V, and 5V power supplies, with a reset threshold voltage of 2.63V at room temperature and a reset active timeout of 560ms. The monitor is immune to transient voltage fluctuations, with a very low supply current of 2.7µA at 3.6V and no external components needed, saving board space. It includes a debounced manual reset input and ensures system robustness by asserting reset signals when VCC drops below the threshold, and keeping it active for 140ms after VCC recovers. Suitable for system monitoring, portable devices, and microcontroller power management, it operates over a temperature range of -40°C to 85°C, with a minimum supply voltage of 1.2V and transient immunity features.
