Detailed Pin Configuration

The MAX809MEUR+T10 is a three-pin device with the following pin configuration:

• Pin 1: GND (Ground)
• Pin 2: RESET (Reset Output)
• Pin 3: VCC (Supply Voltage)

Functional Features

• Precision voltage monitor for microprocessors and digital systems
• Monitors power supply voltage and asserts reset when it falls below the threshold
• Adjustable reset threshold voltage and timeout period options
• Low quiescent current consumption
• Open-drain RESET output allows easy interfacing with various logic levels

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with different systems - Adjustable reset threshold and timeout options provide flexibility - Low quiescent current consumption helps conserve power - Open-drain RESET output simplifies interfacing

Disadvantages: - Limited number of reset threshold voltage and timeout period options - SOT-23-3 package may not be suitable for all applications requiring voltage supervisors

Working Principles

The MAX809MEUR+T10 operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a power failure or brownout condition. The reset remains active until the voltage rises above the threshold and the timeout period elapses.

Detailed Application Field Plans

The MAX809MEUR+T10 is commonly used in various applications, including: - Microprocessor-based systems - Embedded systems - Industrial control systems - Consumer electronics - Battery-powered devices
