```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Digital Output (RESET OUT) |___________| ```

Functional Features

• Monitors the input voltage and compares it with the user-adjustable threshold voltage.
• When the input voltage falls below the threshold, the digital output goes low.
• The output remains low until the input voltage rises above the threshold again.
• Provides a reliable reset signal for microcontrollers, ASICs, and other digital systems.

Advantages

• Low quiescent current makes it suitable for battery-powered applications.
• Adjustable threshold voltage allows flexibility in monitoring different voltage levels.
• High accuracy ensures precise voltage monitoring.
• Small package size (SOT23-3) saves board space.

Disadvantages

• Limited to monitoring voltage levels within the supply voltage range.
• Output is active-low open-drain, which may require additional circuitry for certain applications.

Working Principles

The MAX6382XR17D3-T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage drops below the threshold, the digital output goes low, indicating a reset condition. The output remains low until the input voltage rises above the threshold again. This voltage monitoring function ensures reliable operation of microcontrollers, ASICs, and other digital systems.

Application Field Plans

The MAX6382XR17D3-T can be used in various applications where voltage monitoring is critical. Some potential application fields include:

1. Battery-Powered Devices: Ensuring proper shutdown or hibernation when the battery voltage drops below a certain level.
2. Power Management Systems: Monitoring power supply voltages to protect sensitive components from undervoltage conditions.
3. Industrial Control Systems: Providing reset signals to microcontrollers in industrial automation and control systems.
4. Automotive Electronics: Monitoring automotive battery voltage to prevent deep discharge and ensure proper functioning of vehicle electronics.

Alternative Models

• MAX6382XR17D5-T: Same functionality but with a different threshold voltage range (adjustable from 0.4V to 5V in 50mV steps).
• MAX6382XR17D1-T: Same functionality but with a fixed threshold voltage of 1.7V.
