The MAX809REUR+T is a microprocessor reset circuit manufactured by MAXIM (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

Specifications:

• Manufacturer: MAXIM (Analog Devices)
• Type: Voltage Monitor / Reset Circuit
• Reset Threshold Voltage Options: Adjustable or fixed (e.g., 2.63V, 3.08V, 4.38V, etc., depending on variant)
• Operating Voltage Range: 1.2V to 5.5V
• Reset Timeout Period: Typically 140ms (min) to 280ms (max)
• Output Type: Active-low RESET (open-drain or push-pull, depending on variant)
• Package: SOT-23-3
• Operating Temperature Range: -40°C to +85°C

Descriptions:

• The MAX809REUR+T is a low-power voltage monitor designed to provide a reset signal to microprocessors or digital systems when the supply voltage drops below a preset threshold.
• It ensures proper system initialization by holding the reset signal active until the voltage stabilizes.
• Available in fixed or adjustable threshold versions.

Features:

• Low Quiescent Current: Typically 5µA (helps in power-sensitive applications).
• Precision Voltage Monitoring: Ensures reliable reset operation.
• Manual Reset Input (if applicable): Some variants include a manual reset pin.
• Small Form Factor: SOT-23-3 package for space-constrained designs.
• Wide Operating Voltage Range: Supports 1.2V to 5.5V systems.
