Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage falls below the specified threshold.
• Provides a manual reset input for external control.
• Low-power consumption for efficient operation.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile applications. - Multiple reset threshold and timeout period options provide flexibility. - Low-power operation helps conserve energy.

Disadvantages: - Limited number of available package options. - Lack of built-in protection features against voltage spikes or transients.

Working Principles

The MAX705ESA+TGA5 operates by monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the preset threshold, the reset output is activated, indicating a power failure. The manual reset input allows for external control to initiate a reset signal. The IC operates with low power consumption, making it suitable for battery-powered devices.
