Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
• Provides an adjustable reset timeout period to ensure proper system initialization.
• Offers a manual reset input for external system reset control.
• Generates a power-on reset delay to allow stable power supply before releasing the reset signal.

Advantages and Disadvantages

Advantages: - Low quiescent current enables power-efficient operation. - Wide supply voltage range allows compatibility with various systems. - Adjustable reset timeout period provides flexibility in system initialization. - Small package size saves board space.

Disadvantages: - Limited threshold voltage options may not suit all applications. - Lack of additional features compared to more advanced voltage supervisors.

Working Principles

The MAX16029TG+T operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the supply voltage drops below the selected threshold voltage, the reset output is asserted low. The reset signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses. The manual reset input allows external control over the reset signal.
