Pin Configuration

The MAX705EUA+T has the following pin configuration:

1. GND: Ground
2. RESET: Active-low reset output
3. MR: Manual reset input
4. VCC: Positive supply voltage
5. TH: Threshold voltage selection input
6. TO: Reset timeout period selection input
7. NC: No connection
8. VCC: Positive supply voltage

Functional Features

• Precision voltage monitoring with selectable threshold options
• Adjustable reset timeout period for flexibility in system design
• Manual reset input for external reset control
• Low quiescent current for power efficiency
• Wide supply voltage range for compatibility with various systems

Advantages

• Provides reliable power supply monitoring, ensuring proper system operation
• Flexible threshold and timeout period options for customization
• Low power consumption extends battery life in portable applications
• Small form factor package saves board space
• Easy integration into existing designs due to wide supply voltage range

Disadvantages

• Limited to monitoring only the power supply voltage, does not provide other supervisory functions
• Manual reset input may require additional external components for proper functionality in some applications

Working Principles

The MAX705EUA+T operates by continuously monitoring the power supply voltage. When the voltage drops below the selected threshold, the device asserts the active-low reset output, signaling a system reset. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses.
