The MAX809REUR+T is a microprocessor supervisory circuit from Analog Devices, designed to monitor power supplies in digital systems. It provides reliable power monitoring with a preset reset threshold of 2.63V. When the VCC supply voltage drops below this threshold, the circuit asserts a reset signal, maintaining it for at least 140ms after VCC rises above the threshold.
This supervisor IC features an active-low, push-pull totem pole output and is guaranteed to provide a valid reset signal down to 1V VCC. It requires no external components and operates with a low supply current of 12μA, making it suitable for portable and battery-powered equipment. The device is housed in a compact SOT-23-3 surface-mount package.
Key applications include critical μP and μC power monitoring, automotive systems, computers, controllers, and intelligent instruments. Its robust design ensures power supply transient immunity and full specification over temperature.
