---

| | --| RESET | --| GND | --| MR | --| VCC | --| RESET_OUT | |___________| ```

Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the specified threshold.
• Provides a debounced reset output that remains asserted until the supply voltage rises above the threshold and the reset timeout period elapses.
• Offers a manual reset input (MR) for immediate system reset.
• Low quiescent current consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various power supply configurations.

Advantages and Disadvantages

Advantages: - Compact size and SOT23 package make it suitable for space-constrained designs. - Low-power operation helps conserve energy in battery-powered applications. - Multiple reset threshold and timeout options provide flexibility for different system requirements.

Disadvantages: - Limited number of available reset threshold and timeout combinations. - Not suitable for high-voltage applications due to the maximum supply voltage limitation.

Working Principles

The MAX16034LLB31+T operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the reset output is asserted. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses. The manual reset input (MR) allows for an immediate system reset when triggered.
