---

| | --| VCC | --| MR | --| GND | --| RESET | --| RESETB| |_______| ```

• VCC: Supply voltage input
• MR: Manual reset input (active-low)
• GND: Ground reference
• RESET: Active-high reset output
• RESETB: Active-low reset output

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the set threshold.
• Adjustable reset threshold allows customization for different system requirements.
• Provides both active-high and active-low reset outputs for flexibility in system design.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring helps prevent system malfunctions. - Adjustable reset threshold accommodates various voltage levels. - Small package size saves board space. - Low-power operation extends battery life in portable devices.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited number of available reset threshold options.

Working Principles

The MAX6388XS46D1-T operates by continuously monitoring the supply voltage through an internal voltage reference. When the voltage falls below the set threshold, the reset circuit triggers and generates a reset signal. This signal can be used to initiate system initialization or recovery processes. The reset circuit remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
