The MAX812TEUS+T is a low-power microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a precise monitoring of 3.08V power-supply voltages and asserts an active-high reset signal when the VCC supply voltage falls below this threshold. The reset signal is held asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring system stability during power fluctuations.
This device is ideal for 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 MAX812TEUS+T comes in a compact 4-pin SOT-143 package, suitable for space-constrained applications. It operates over a temperature range of -40°C to 85°C.
Key features include a guaranteed reset valid down to 1V for the MAX811 variant (though this is the MAX812 with active-high reset). The reset comparator is designed to ignore fast transients on VCC, further enhancing system reliability. This component is well-suited for critical μP and μC power monitoring applications in computers, controllers, and intelligent instruments.
