Functional Features

• Monitors the power supply voltage and provides a reset signal when the voltage falls below a specified threshold.
• Active-low reset output ensures compatibility with various microcontrollers and digital systems.
• Precision voltage monitoring ensures reliable system operation.
• Low quiescent current consumption helps in power-sensitive applications.

Advantages

• Wide supply voltage range allows for versatile usage in different electronic systems.
• Multiple reset threshold voltage options provide flexibility to meet specific requirements.
• Reset timeout period ensures proper system reset and prevents false triggering.
• Low quiescent current consumption helps in prolonging battery life in portable devices.

Disadvantages

• Limited number of available reset threshold voltage options.
• Lack of adjustable reset timeout period may not suit all application scenarios.
• Only supports active-low reset output, limiting compatibility with systems requiring active-high reset.

Working Principles

The MAX705CPA operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the IC asserts an active-low reset signal. This signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses. The precision voltage monitoring ensures that the system is reliably reset when necessary.
