Description

The MAX823SEUK+T is a microprocessor supervisory circuit manufactured by Maxim Integrated, designed to monitor the power supply to microprocessors and digital systems. It ensures system reliability by providing features such as reset output, watchdog timer, and manual reset input. The device operates by monitoring the voltage level of the power supply and generating a reset signal when the voltage drops below a specified threshold, ensuring that the microprocessor starts correctly once the power is stable.
Key features of the MAX823SEUK+T include a low supply current, typically around a few microamperes, making it suitable for battery-powered applications. It also offers a precision monitoring capability with specified voltage thresholds, ensuring accurate performance. The watchdog timer can be used to reset the system if the microprocessor fails to operate correctly within a predetermined time frame. The MAX823SEUK+T is housed in a compact SOT23-5 package, making it ideal for space-constrained applications. This device is commonly used in consumer electronics, industrial controls, and portable devices where reliable power monitoring and system reset functionality are critical.

Features
