The MAX823EUK from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

Key Features

  • Precision Monitoring: This device features precision voltage monitoring that ensures systems are operating at optimal voltages, thereby enhancing overall system stability.
  • Power-On Reset: The MAX823EUK offers a power-on reset feature that asserts a reset signal whenever the supply voltage falls below a preset threshold, ensuring the µP starts up in a known state.
  • Manual Reset: A manual reset input is provided, allowing the user to trigger a reset with an external push-button or logic signal, offering additional control over system reset events.
  • Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit consumes minimal power, which is crucial for battery-operated devices.
  • Compact SOT23 Package: The device is available in a small SOT23-5 package, making it ideal for space-constrained applications without compromising performance.


The MAX823EUK is suitable for a wide range of applications, including:

  • Portable/Battery-Powered Equipment
  • Computers and Controllers
  • Embedded Systems
  • Intelligent Instruments
  • Critical µP and µC Power Monitoring

Technical Specifications

The device operates with a supply voltage range from +1.2V to +5.5V, making it versatile for various digital systems. It also features a factory-trimmed reset threshold voltage, an active-low RESET output, and a reset timeout period of 140ms (min), ensuring reliable operation during power-up, brownout, and power-down events.


The MAX823EUK supervisory circuit from Maxim Integrated is an essential component for ensuring the reliability and proper function of microprocessor-based systems. Its low power consumption, compact size, and precision voltage monitoring capabilities make it an excellent choice for designers looking to enhance system stability and performance.
