Maxim Integrated MAX811SEUS Microprocessor (µP) Supervisory Circuit

The Maxim Integrated MAX811SEUS is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a crucial safeguard against low voltage, which can lead to system malfunctions, data loss, or even hardware damage. This device is particularly useful in applications where reliable operation is critical, such as in portable devices, computers, controllers, and intelligent instruments.

Key Features

• Precision Monitoring: The MAX811SEUS features a precision voltage monitor with a factory-set reset threshold voltage, ensuring accurate and consistent monitoring of the system voltage.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit operates with low quiescent current, thereby conserving battery life in portable applications.
• Reset Signal: It generates a reset signal whenever the VCC supply voltage falls below the preset threshold, keeping the µP within safe operating conditions. The reset signal remains active until the supply voltage recovers and stabilizes, ensuring the system restarts safely.
• Manual Reset Capability: An additional feature includes a manual reset input, allowing the user to trigger a reset manually, which is useful for system maintenance and troubleshooting.
• Compact SOT-143 Package: The small footprint of the SOT-143 package makes it ideal for space-constrained applications, without compromising on performance and reliability.
