Description

The MAX823REUK+T is a microprocessor supervisory circuit designed to monitor power supply levels in microprocessor and digital systems. Key features include a precision voltage reference and a comparator that triggers a reset when the monitored supply voltage falls below a preset threshold, ensuring the microprocessor is reset during power faults to prevent erratic operation. The "+T" in the part number typically indicates the packaging type or compliance with specific industry standards.
This device offers a reset output, which remains active for a specified duration after the voltage returns to a safe level, allowing the system to stabilize before normal operation resumes. The MAX823REUK+T is also equipped with features like a manual reset input, a low supply current design, and a push-pull output. It is available in compact surface-mount packages, which makes it suitable for space-constrained applications. Ideal for use in battery-powered systems, it provides essential monitoring functions to enhance system reliability and safety.
