The MAX812LEUS-T is a microprocessor supervisory circuit from Analog Devices, designed to monitor power supplies in digital systems. It provides a reset signal when the VCC supply voltage falls below a preset threshold, ensuring system stability.
Key electrical specifications include a nominal reset threshold voltage of 4.63V and a minimum power-on reset pulse width of 140ms. The device operates over a temperature range of -40°C to 85°C. It features an active-high reset output and is designed to ignore fast transients on VCC, enhancing system robustness.
This supervisory circuit 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. The MAX812LEUS-T comes in a compact 4-pin SOT-143-4 package, suitable for space-constrained designs.
It offers precision monitoring for 3V, 3.3V, and 5V power-supply voltages, with a guaranteed reset valid down to 1V for the MAX811 variant. The MAX812LEUS-T includes a debounced manual reset input, further increasing system reliability.
