Maxim Integrated MAX823REUK-T Microprocessor Supervisor IC

The MAX823REUK-T from Maxim Integrated is a compact, 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 in battery-powered applications such as computers, controllers, and intelligent instruments.

This microprocessor supervisor IC ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX823REUK-T comes in a tiny 5-pin SOT-23 package, offering a space-saving solution for systems where board space is at a premium.

Key Features

• Supply Voltage Monitoring: The device monitors the system voltage and keeps the microprocessor in the reset state until that voltage reaches an acceptable level for reliable system operation.
• Manual Reset Input: A manual reset input is provided, allowing a pushbutton or external logic to initiate system reset.
• Low Power Consumption: Designed for power-sensitive applications, the MAX823REUK-T consumes minimal power, which is crucial for extending battery life in portable devices.
• Reset Timeout: It features a preset timeout delay, ensuring the microprocessor is held in the reset state for a sufficient period to allow the system to stabilize.

Applications

• Portable/Battery-Powered Equipment
• Embedded Systems
• Computers and Servers
• Industrial Controllers
• Intelligent Instruments

The MAX823REUK-T is designed to improve the reliability of a digital system by providing several key protective features.
