Maxim Integrated's MAX811TEUS+ Microprocessor (µP) Supervisory Circuit

The MAX811TEUS+ from Maxim Integrated is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of protection to ensure stable and reliable operation. This supervisory circuit is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and portable battery-powered electronics.

Key Features

• Precision Monitoring: The MAX811TEUS+ offers precise monitoring of its own power supply voltage with a factory-trimmed reset threshold level. This ensures that the µP resets consistently at the appropriate voltage, preventing any erratic behavior due to power supply fluctuations.
• Manual Reset Input: This feature allows for a manual reset, enabling the system to be reset on demand, which is particularly useful during system troubleshooting or for initiating a known startup state.
• Low Power Consumption: With its low quiescent current, the MAX811TEUS+ is a power-efficient choice for battery-operated devices, helping to extend battery life and reduce energy consumption.
• Reset Timeout: The device has a 140ms minimum power-on reset timeout period, which provides ample time for the system to stabilize before the µP starts its operation.
• Active-Low Reset Output: The active-low reset output ensures compatibility with a wide range of µP and microcontroller (MCU) architectures by providing a logic-low signal during reset conditions.
• Small SOT-143 Package: The compact SOT-143 package allows for efficient use of board space, making it suitable for space-constrained applications.
