Detailed Pin Configuration

The MAX809SEUR+TG05 has three pins:

1. GND: Ground pin
2. RESET: Reset output pin
3. VCC: Power supply input pin

Functional Features

• Monitors the power supply voltage continuously
• Generates a reset signal when the voltage drops below the specified threshold
• Provides a stable reset output during power-up and power-down sequences
• Low quiescent current ensures minimal power consumption
• Wide operating voltage range allows compatibility with various systems

Advantages

• Precise voltage monitoring ensures reliable system operation
• Low-power consumption extends battery life in portable devices
• Small SOT-23-3 package saves board space
• Wide operating voltage range provides flexibility in different applications

Disadvantages

• Limited reset threshold and timeout period options may not suit all system requirements
• SOT-23-3 package may be challenging to solder for inexperienced users

Working Principles

The MAX809SEUR+TG05 operates by comparing the power supply voltage with a fixed threshold. When the voltage drops below the threshold, the internal circuitry triggers a reset signal. This signal remains active until the voltage rises above the threshold or power is removed.

Detailed Application Field Plans

The MAX809SEUR+TG05 is commonly used in various electronic systems that require reliable voltage monitoring and reset functionality. Some application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial control systems
4. Power management circuits
5. Battery-powered devices
