Maxim Integrated MAX6823TUK Microprocessor Supervisory Circuits

The Maxim Integrated MAX6823TUK is a compact, high-precision microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 1.8V to 5.0V.

Key Features

• Reset Timeout: The MAX6823TUK offers a preset timeout period of 140ms, ensuring that the µP has sufficient time to initialize after power-up or during a brownout condition.
• Voltage Monitoring: This device monitors the system voltage and asserts a reset if the monitored voltage drops below the factory-set reset threshold, helping to maintain system integrity.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6823TUK features low quiescent current, typically 5µA, making it suitable for battery-operated devices.
• Manual Reset Input: It includes a manual reset input that allows for a system reset to be triggered with an external pushbutton or logic signal.
• Compact SOT23 Packaging: The device comes in a small 5-pin SOT23 package, making it ideal for space-constrained applications.
