Specifications

• Supply Voltage Range: 1.0V to 5.5V
• Threshold Voltage Options: 2.32V, 2.63V, 2.93V, 3.08V, 3.63V, 4.38V
• Reset Timeout Period: 140ms, 560ms, 1120ms, 2240ms
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX809SEUR+TG24 has three pins:

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

Functional Features

• Low quiescent current consumption
• Precision monitoring of power supply voltage
• Manual reset input for system initialization
• Watchdog timer for detecting system malfunctions
• Adjustable threshold voltage options
• Open drain or push-pull reset output options

Advantages and Disadvantages

Advantages: - Low power consumption - Wide supply voltage range - Adjustable threshold voltage - Small package size

Disadvantages: - Limited reset timeout period options - Lack of additional features like power-on reset delay

Working Principles

The MAX809SEUR+TG24 operates by continuously monitoring the supply voltage. When the voltage drops below the specified threshold, the reset output is activated, signaling a system reset. The reset output remains active until the supply voltage rises above the threshold again.

Detailed Application Field Plans

The MAX809SEUR+TG24 is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some potential application fields include:

1. Microcontroller-based systems
2. Industrial control systems
3. Battery-powered devices
4. Embedded systems
5. Automotive electronics
