The MAX809SEUR+T is a microprocessor supervisory circuit from Analog Devices, designed for monitoring power supplies in digital systems. It asserts a reset signal when the VCC supply voltage falls below a preset threshold, maintaining the reset for at least 140ms after VCC rises above the threshold. This device is suitable for +5V, +3.3V, +3.0V, or +2.5V powered circuits.
Key electrical characteristics include a nominal operating voltage of 2.93V, an active-low push-pull reset output, and a reset timeout of 140ms minimum. The circuit guarantees a valid reset down to VCC = 1V and offers power supply transient immunity. It operates with a low supply current of 12μA, making it ideal for portable equipment.
The MAX809SEUR+T is available in a 3-pin SOT-23-3 package, suitable for surface mount applications. Its compact size and low power consumption make it a reliable choice for critical μP and μC power monitoring in computers, controllers, intelligent instruments, and automotive applications.
