The MAX809MEUR+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It is designed to monitor power supplies in microprocessor and digital systems, ensuring reliable operation by asserting a reset signal when the VCC supply voltage falls below a preset threshold. This circuit features a precise monitoring voltage of 4.38V and a minimum reset timeout pulse width of 140ms.
The MAX809MEUR+T has an active-low, push-pull output and is capable of monitoring a single voltage supply. It is guaranteed to maintain a valid reset state even when VCC drops as low as 1V, offering robust performance against power supply transients. With a low supply current of 12μA, it is suitable for portable and battery-powered equipment.
This component is supplied in a compact SOT-23-3 package, suitable for surface mount applications. The operating temperature range is from -40°C to 105°C (TA). Its primary function is to provide critical μP and μC power monitoring, contributing to system reliability in applications such as computers, controllers, and intelligent instruments.
