The MAX824TEXK+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

Specifications:

• Manufacturer: Maxim Integrated
• Series: MAX824
• Type: Voltage Monitor / Supervisory Circuit
• Package: SC-70 (SOT-323), 5-Pin
• Operating Voltage Range: 1.2V to 5.5V
• Reset Threshold Options: Adjustable or Fixed (1.6V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)
• Reset Timeout Period: 140ms (min)
• Operating Temperature Range: -40°C to +85°C
• Quiescent Current: 5µA (typical)

Descriptions:

• The MAX824TEXK+T monitors system voltage and provides a reset signal to the microprocessor when the voltage falls below a preset threshold.
• It ensures proper system initialization by holding the reset signal active for a fixed delay after power-up or brownout conditions.
• Available in small SC-70 (SOT-323) packages, making it suitable for space-constrained applications.

Features:

• Low-Power Operation: Consumes only 5µA (typical) for battery-powered applications.
• Manual Reset Input: Allows external pushbutton reset control.
• Power-On Reset (POR): Guarantees a valid reset signal at power-up.
• Wide Operating Voltage Range (1.2V to 5.5V): Supports various logic levels.
• Fixed or Adjustable Reset Threshold: Multiple preset options available.
• Small Form Factor: 5-pin SC-70 package for compact designs.

This device is commonly used in embedded systems, industrial controls, automotive electronics, and battery-powered devices where reliable voltage monitoring is critical.
