The MAX6821SUK-T is a microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

Key Features

• Precision Monitoring: The device features a precision voltage monitor that keeps a watchful eye on the system's power supply, ensuring that it operates within acceptable limits.
• Reset Output: Upon detecting an out-of-tolerance condition, the MAX6821SUK-T asserts a reset signal to the µP, holding it in reset for a minimum of 140ms after the voltage returns to an acceptable level. This ensures the system has adequate time to stabilize before resuming operation.
• Low Power Consumption: With its low supply current draw, this supervisory IC is an ideal choice for power-sensitive applications.
• Compact SOT23 Packaging: The device comes in a small-outline transistor (SOT23) package, making it suitable for space-constrained applications.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered with an external switch or logic signal.
• Temperature Range: The MAX6821SUK-T operates over an extended temperature range, making it versatile for various environments and applications.
